+ About this README
+------------------------------------------------------------
+
+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+ 
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:
+
+    http://guac-dev.org/
+
+
+------------------------------------------------------------
+ What is guacamole-client?
+------------------------------------------------------------
+
+guacamole-client is the superproject containing all Maven-based projects that
+make Guacamole, an HTML5 web application that provides access to your desktop
+using remote desktop protocols.
+
+guacamole-client is used to build the subprojects that make up Guacamole, and
+to provide a common central repository. Each project contained here is
+completely independent of guacamole-client and can be built separately, though
+the others may have to be built first. If all projects are built using
+guacamole-client, Maven will take care of the proper build order.
+
+
+------------------------------------------------------------
+ Compiling and installing Guacamole
+------------------------------------------------------------
+
+Guacamole is built using Maven. Building Guacamole compiles all classes and
+packages them into a deployable .war file. This .war file can be installed
+and deployed under servlet containers like Apache Tomcat or Jetty.
+
+1) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .war file will be
+    created in the guacamole/target/ subdirectory of the current directory.
+
+2) Copy the .war file as directed in the instructions provided with
+   your servlet container.
+
+   Apache Tomcat, Jetty, and other servlet containers have specific and
+   varying locations that .war files must be placed for the web
+   application to be deployed.
+
+   You will likely need to do this as root.
+

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+     extent possible, whether at the time of the initial grant or
+     subsequently acquired, any and all of the rights conveyed herein.
+
+     1.9. "Modifications" means any addition to or deletion from the
+     substance or structure of either the Original Code or any previous
+     Modifications. When Covered Code is released as a series of files, a
+     Modification is:
+          A. Any addition to or deletion from the contents of a file
+          containing Original Code or previous Modifications.
+
+          B. Any new file that contains any part of the Original Code or
+          previous Modifications.
+
+     1.10. "Original Code" means Source Code of computer software code
+     which is described in the Source Code notice required by Exhibit A as
+     Original Code, and which, at the time of its release under this
+     License is not already Covered Code governed by this License.
+
+     1.10.1. "Patent Claims" means any patent claim(s), now owned or
+     hereafter acquired, including without limitation,  method, process,
+     and apparatus claims, in any patent Licensable by grantor.
+
+     1.11. "Source Code" means the preferred form of the Covered Code for
+     making modifications to it, including all modules it contains, plus
+     any associated interface definition files, scripts used to control
+     compilation and installation of an Executable, or source code
+     differential comparisons against either the Original Code or another
+     well known, available Covered Code of the Contributor's choice. The
+     Source Code can be in a compressed or archival form, provided the

+     for no charge.
+
+     1.12. "You" (or "Your")  means an individual or a legal entity

+     entity.
+
+2. Source Code License.
+
+     2.1. The Initial Developer Grant.
+     The Initial Developer hereby grants You a world-wide, royalty-free,
+     non-exclusive license, subject to third party intellectual property
+     claims:
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Initial Developer to use, reproduce,
+          modify, display, perform, sublicense and distribute the Original
+          Code (or portions thereof) with or without Modifications, and/or
+          as part of a Larger Work; and
+
+          (b) under Patents Claims infringed by the making, using or
+          selling of Original Code, to make, have made, use, practice,
+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+
+          (c) the licenses granted in this Section 2.1(a) and (b) are
+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license is
+          granted: 1) for code that You delete from the Original Code; 2)
+          separate from the Original Code;  or 3) for infringements caused
+          by: i) the modification of the Original Code or ii) the
+          combination of the Original Code with other software or devices.
+
+     2.2. Contributor Grant.
+     Subject to third party intellectual property claims, each Contributor
+     hereby grants You a world-wide, royalty-free, non-exclusive license
+
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Contributor, to use, reproduce, modify,
+          display, perform, sublicense and distribute the Modifications
+          created by such Contributor (or portions thereof) either on an
+          unmodified basis, with other Modifications, as Covered Code
+          and/or as part of a Larger Work; and
+
+          (b) under Patent Claims infringed by the making, using, or
+          selling of  Modifications made by that Contributor either alone
+          and/or in combination with its Contributor Version (or portions
+          of such combination), to make, use, sell, offer for sale, have
+          made, and/or otherwise dispose of: 1) Modifications made by that
+          Contributor (or portions thereof); and 2) the combination of
+          Modifications made by that Contributor with its Contributor
+          Version (or portions of such combination).
+
+          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
+          effective on the date Contributor first makes Commercial Use of
+          the Covered Code.
+
+          (d)    Notwithstanding Section 2.2(b) above, no patent license is
+          granted: 1) for any code that Contributor has deleted from the
+          Contributor Version; 2)  separate from the Contributor Version;
+          3)  for infringements caused by: i) third party modifications of
+          Contributor Version or ii)  the combination of Modifications made
+          by that Contributor with other software  (except as part of the
+          Contributor Version) or other devices; or 4) under Patent Claims
+          infringed by Covered Code in the absence of Modifications made by
+          that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.
+     The Modifications which You create or to which You contribute are
+     governed by the terms of this License, including without limitation
+     Section 2.2. The Source Code version of Covered Code may be
+     distributed only under the terms of this License or a future version
+     of this License released under Section 6.1, and You must include a
+     copy of this License with every copy of the Source Code You
+     distribute. You may not offer or impose any terms on any Source Code
+     version that alters or restricts the applicable version of this
+     License or the recipients' rights hereunder. However, You may include
+     an additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.
+     Any Modification which You create or to which You contribute must be
+     made available in Source Code form under the terms of this License
+     either on the same media as an Executable version or via an accepted
+     Electronic Distribution Mechanism to anyone to whom you made an
+     Executable version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve (12)
+     months after the date it initially became available, or at least six
+     (6) months after a subsequent version of that particular Modification
+     has been made available to such recipients. You are responsible for
+     ensuring that the Source Code version remains available even if the
+     Electronic Distribution Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.
+     You must cause all Covered Code to which You contribute to contain a
+     file documenting the changes You made to create that Covered Code and
+     the date of any change. You must include a prominent statement that
+     the Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of the
+     Initial Developer in (a) the Source Code, and (b) in any notice in an
+     Executable version or related documentation in which You describe the
+     origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters
+          (a) Third Party Claims.
+          If Contributor has knowledge that a license under a third party's
+          intellectual property rights is required to exercise the rights
+          granted by such Contributor under Sections 2.1 or 2.2,
+          Contributor must include a text file with the Source Code
+          distribution titled "LEGAL" which describes the claim and the
+          party making the claim in sufficient detail that a recipient will
+          know whom to contact. If Contributor obtains such knowledge after
+          the Modification is made available as described in Section 3.2,
+          Contributor shall promptly modify the LEGAL file in all copies
+          Contributor makes available thereafter and shall take other steps
+          (such as notifying appropriate mailing lists or newsgroups)
+          reasonably calculated to inform those who received the Covered
+          Code that new knowledge has been obtained.
+
+          (b) Contributor APIs.
+          If Contributor's Modifications include an application programming
+          interface and Contributor has knowledge of patent licenses which
+          are reasonably necessary to implement that API, Contributor must
+          also include this information in the LEGAL file.
+
+               (c)    Representations.
+          Contributor represents that, except as disclosed pursuant to
+          Section 3.4(a) above, Contributor believes that Contributor's
+          Modifications are Contributor's original creation(s) and/or
+          Contributor has sufficient rights to grant the rights conveyed by
+          this License.
+
+     3.5. Required Notices.
+     You must duplicate the notice in Exhibit A in each file of the Source
+     Code.  If it is not possible to put such notice in a particular Source
+     Code file due to its structure, then You must include such notice in a
+     location (such as a relevant directory) where a user would be likely
+     to look for such a notice.  If You created one or more Modification(s)
+     You may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any documentation
+     for the Source Code where You describe recipients' rights or ownership
+     rights relating to Covered Code.  You may choose to offer, and to
+     charge a fee for, warranty, support, indemnity or liability
+     obligations to one or more recipients of Covered Code. However, You
+     may do so only on Your own behalf, and not on behalf of the Initial
+     Developer or any Contributor. You must make it absolutely clear than
+     any such warranty, support, indemnity or liability obligation is
+     offered by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.
+     You may distribute Covered Code in Executable form only if the
+     requirements of Section 3.1-3.5 have been met for that Covered Code,
+     and if You include a notice stating that the Source Code version of
+     the Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously included
+     in any notice in an Executable version, related documentation or
+     collateral in which You describe recipients' rights relating to the
+     Covered Code. You may distribute the Executable version of Covered
+     Code or ownership rights under a license of Your choice, which may
+     contain terms different from this License, provided that You are in
+     compliance with the terms of this License and that the license for the
+     Executable version does not attempt to limit or alter the recipient's
+     rights in the Source Code version from the rights set forth in this
+     License. If You distribute the Executable version under a different
+     license You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability incurred by
+     the Initial Developer or such Contributor as a result of any such
+     terms You offer.
+
+     3.7. Larger Works.
+     You may create a Larger Work by combining Covered Code with other code
+     not governed by the terms of this License and distribute the Larger
+     Work as a single product. In such a case, You must make sure the
+     requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of this
+     License with respect to some or all of the Covered Code due to
+     statute, judicial order, or regulation then You must: (a) comply with
+     the terms of this License to the maximum extent possible; and (b)
+     describe the limitations and the code they affect. Such description
+     must be included in the LEGAL file described in Section 3.4 and must
+     be included with all distributions of the Source Code. Except to the
+     extent prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be able to
+     understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.
+     Netscape Communications Corporation ("Netscape") may publish revised
+     and/or new versions of the License from time to time. Each version
+     will be given a distinguishing version number.
+
+     6.2. Effect of New Versions.
+     Once Covered Code has been published under a particular version of the
+     License, You may always continue to use it under the terms of that
+     version. You may also choose to use such Covered Code under the terms
+     of any subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable to
+     Covered Code created under this License.
+
+     6.3. Derivative Works.
+     If You create or use a modified version of this License (which you may
+     only do in order to apply it to code which is not already Covered Code
+     governed by this License), You must (a) rename Your license so that
+     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+     "MPL", "NPL" or any confusingly similar phrase do not appear in your
+     license (except to note that your license differs from this License)
+     and (b) otherwise make it clear that Your version of the license
+     contains terms which differ from the Mozilla Public License and
+     Netscape Public License. (Filling in the name of the Initial
+     Developer, Original Code or Contributor in the notice described in
+     Exhibit A shall not of themselves be deemed to be modifications of
+     this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will terminate
+     automatically if You fail to comply with terms herein and fail to cure
+     such breach within 30 days of becoming aware of the breach. All
+     sublicenses to the Covered Code which are properly granted shall
+     survive any termination of this License. Provisions which, by their
+     nature, must remain in effect beyond the termination of this License
+     shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent infringement
+     claim (excluding declatory judgment actions) against Initial Developer
+     or a Contributor (the Initial Developer or Contributor against whom
+     You file such action is referred to as "Participant")  alleging that:
+
+     (a)  such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate prospectively,
+     unless if within 60 days after receipt of notice You either: (i)
+     agree in writing to pay Participant a mutually agreeable reasonable
+     royalty for Your past and future use of Modifications made by such
+     Participant, or (ii) withdraw Your litigation claim with respect to
+     the Contributor Version against such Participant.  If within 60 days
+     of notice, a reasonable royalty and payment arrangement are not
+     mutually agreed upon in writing by the parties or the litigation claim
+     is not withdrawn, the rights granted by Participant to You under
+     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+     the 60 day notice period specified above.
+
+     (b)  any software, hardware, or device, other than such Participant's
+     Contributor Version, directly or indirectly infringes any patent, then
+     any rights granted to You by such Participant under Sections 2.1(b)
+     and 2.2(b) are revoked effective as of the date You first made, used,
+     sold, distributed, or had made, Modifications made by that
+     Participant.
+
+     8.3.  If You assert a patent infringement claim against Participant
+     alleging that such Participant's Contributor Version directly or
+     indirectly infringes any patent where such claim is resolved (such as
+     by license or settlement) prior to the initiation of patent
+     infringement litigation, then the reasonable value of the licenses
+     granted by such Participant under Sections 2.1 or 2.2 shall be taken
+     into account in determining the amount or value of any payment or
+     license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
+     all end user license agreements (excluding distributors and resellers)
+     which have been validly granted by You or any distributor hereunder
+     prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
+     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
+     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+     The Covered Code is a "commercial item," as that term is defined in
+     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+     software" and "commercial computer software documentation," as such
+     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
+     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
+     all U.S. Government End Users acquire Covered Code with only those
+     rights set forth herein.
+
+11. MISCELLANEOUS.
+
+     This License represents the complete agreement concerning subject
+     matter hereof. If any provision of this License is held to be
+     unenforceable, such provision shall be reformed only to the extent
+     necessary to make it enforceable. This License shall be governed by
+     California law provisions (except to the extent applicable law, if
+     any, provides otherwise), excluding its conflict-of-law provisions.
+     With respect to disputes in which at least one party is a citizen of,
+     or an entity chartered or registered to do business in the United
+     States of America, any litigation relating to this License shall be
+     subject to the jurisdiction of the Federal Courts of the Northern
+     District of California, with venue lying in Santa Clara County,
+     California, with the losing party responsible for costs, including
+     without limitation, court costs and reasonable attorneys' fees and
+     expenses. The application of the United Nations Convention on
+     Contracts for the International Sale of Goods is expressly excluded.
+     Any law or regulation which provides that the language of a contract
+     shall be construed against the drafter shall not apply to this
+     License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+     As between Initial Developer and the Contributors, each party is
+     responsible for claims and damages arising, directly or indirectly,
+     out of its utilization of rights under this License and You agree to
+     work with Initial Developer and Contributors to distribute such
+     responsibility on an equitable basis. Nothing herein is intended or
+     shall be deemed to constitute any admission of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+     Initial Developer may designate portions of the Covered Code as
+     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial
+     Developer permits you to utilize portions of the Covered Code under
+     Your choice of the NPL or the alternative licenses, if any, specified
+     by the Initial Developer in the file described in Exhibit A.

+ About this README
+------------------------------------------------------------
+
+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+ 
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:

+ What is guacamole-auth-ldap?
+------------------------------------------------------------
+
+guacamole-auth-ldap is a Java library for use with the Guacamole web
+application to provide LDAP based authentication.
+
+guacamole-auth-ldap provides an authentication provider which can be
+set in guacamole.properties to allow LDAP authentication of Guacamole
+users. Additional properties are required to configure the LDAP
+connection and search parameters.
+
+Schema files are provided to create the required object classes in your
+LDAP directory.
+
+
+------------------------------------------------------------
+ Compiling and installing guacamole-auth-ldap
+------------------------------------------------------------
+
+guacamole-auth-ldap is built using Maven. Building guacamole-auth-ldap
+compiles all classes and packages them into a redistributable .jar file. This
+.jar file can be installed in the library directory configured in
+guacamole.properties such that the authentication provider is available.

+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .jar file will be
+    created in the target/ subdirectory of the current directory.
+
+2) Copy the .jar file into the library directory specified in your
+   guacamole.properties
+
+    You will likely need to do this as root.
+
+    If you do not have a library directory configured in your
+    guacamole.properties, you will need to specify one. The directory
+    is specified using the "lib-directory" property.
+
+3) Set up your LDAP server to authenticate Guacamole users
+
+    Schema files are provided in the doc directory for creating
+    the "guacConfig" object class required.
+
+    You must add guacConfig objects to your LDAP directory. Each
+    guacConfig represents a connection configuration, which is made
+    up of a protocol and any number of protocol-specific parameters.
+
+4) Configure guacamole.properties for LDAP
+
+    There are additional properties required by the LDAP authentication
+    provider which must be added/changed in your guacamole.properties:
+
+    # Use LDAP authentication
+    auth-provider: net.sourceforge.guacamole.net.auth.ldap.LDAPAuthenticationProvider
+
+    # Configuration for LDAP connection
+    ldap-hostname:           LDAP_SERVER_HOSTNAME
+    ldap-port:               389
+
+    # The attribute which uniquely identifies users
+    ldap-username-attribute: uid
+
+    # The base DN which, when appended to the user identifier attribute,
+    # produces the full DN of the user being authenticated.
+    ldap-user-base-dn:       ou=people,dc=example,dc=net
+
+    # The base DN within which all guacConfig objects can be found.
+    ldap-config-base-dn:     dc=example,dc=net

+------------------------------------------------------------
+ About this README
+------------------------------------------------------------
+
+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+ 
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:
+
+    http://guac-dev.org/
+
+
+------------------------------------------------------------
+ What is guacamole-auth-mysql?
+------------------------------------------------------------
+
+guacamole-auth-ldap is a Java library for use with the Guacamole web
+application to provide MySQL based authentication.
+
+guacamole-auth-mysql provides an authentication provider which can be
+set in guacamole.properties to allow MySQL authentication of Guacamole
+users. Additional properties are required to configure the mysql
+connection parameters.
+
+A schema file are provided to create the required tables in your
+mysql database.
+
+
+------------------------------------------------------------
+ Compiling and installing guacamole-auth-mysql
+------------------------------------------------------------
+
+guacamole-auth-mysql is built using Maven. Building guacamole-auth-mysql
+compiles all classes and packages them into a redistributable .jar file. This
+.jar file can be installed in the library directory configured in
+guacamole.properties such that the authentication provider is available.
+
+1) Set up a MySQL database with the Guacamole schema.
+
+    When guacamole-auth-mysql is compiling, it needs to generate source
+    based on a database schema. Because the source generator uses a
+    connection to an actual database to do this, you must have a MySQL
+    database running with the Guacamole schema set up.
+
+    First, create a database. For the sake of these instructions, we will
+    call the database "guacamole", and will run all scripts as the root user:
+
+    $ mysql -u root -p
+    Enter password:
+    mysql> CREATE DATABASE guacamole;
+    Query OK, 1 row affected (0.00 sec)
+
+    mysql> exit
+    Bye
+
+    The schema files are in the schema/ subdirectory of the source. If run
+    in order, they will create the schema and a default user:
+
+    $ cat schema/*.sql | mysql -u root -p guacamole
+
+2) Set up your ~/.m2/settings.xml
+
+    Once the database is set up, Maven will need to have the credentials
+    required to connect to it and query the schema. This information is
+    specified in properties inside your ~/.m2/settings.xml file. If this
+    file does not exist yet, simply create it.
+
+    For ease of compilation, we've included an example settings.xml
+    defining the required properties in doc/example/settings.xml. You can
+    simply copy this file into ~/.m2 and edit as necessary.
+
+    If you wish to write the file yourself, the file should look like this in
+    general:
+
+    <settings>
+        <profiles>
+            ...profiles...
+        </profiles>
+    </settings>
+
+    We need to add a profile which defines the required properties by
+    placing a section like the following within the "profiles" section of your
+    settings.xml:
+
+    <profile>
+        <id>guacamole-mybatis</id>
+        <properties>
+            <guacamole.database.catalog>DATABASE</guacamole.database.catalog>
+            <guacamole.database.user>USERNAME</guacamole.database.user>
+            <guacamole.database.password>PASSWORD</guacamole.database.password>
+        </properties>
+    </profile>
+
+    Obviously, the DATABASE, USERNAME, and PASSWORD placeholders above must
+    be replaced with the appropriate values for your system.
+
+    Finally, to make the profile available to the build, it must be activated.
+    Place a section like the following at the bottom of your settings.xml,
+    right after the profiles section:
+
+    <activeProfiles>
+        <activeProfile>guacamole-mybatis</activeProfile>
+    </activeProfiles>
+
+    Maven's documentation has more details on writing the settings.xml file
+    if you have different needs or the above directions are not clear.
+
+3) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .jar file will be
+    created in the target/ subdirectory of the current directory.
+
+    If this process fails, check the build errors, and verify that the
+    contents of your settings.xml file is correct.
+
+4) Extract the .tar.gz file now present in the target/ directory, and
+   place the .jar files in the extracted lib/ subdirectory in the library 
+   directory specified in guacamole.properties.
+
+    You will likely need to do this as root.
+
+    If you do not have a library directory configured in your
+    guacamole.properties, you will need to specify one. The directory
+    is specified using the "lib-directory" property.
+
+5) Set up your MySQL database to authenticate Guacamole users
+
+    A schema file is provided in the schema directory for creating
+    the guacamole authentication tables in your MySQL database.
+
+    Additionally, a script is provided to create a default admin user
+    with username 'guacadmin' and password 'guacadmin'. This user can 
+    be used to set up any other connections and users.
+
+6) Configure guacamole.properties for MySQL
+
+    There are additional properties required by the MySQL JDBC driver
+    which must be added/changed in your guacamole.properties:
+
+    # Configuration for MySQL connection
+    mysql-hostname:           mysql.host.name
+    mysql-port:               3306
+    mysql-database:           guacamole.database.name
+    mysql-username:           user
+    mysql-password:           pass
+
+    Optionally, the authentication provider can be configured
+    not to allow multiple users to use the same connection
+    at the same time:
+
+    mysql-disallow-simultaneous-connections: true
+

+
+------------------------------------------------------------
+ About this README
+------------------------------------------------------------
+
+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:
+
+    http://guac-dev.org/
+
+
+------------------------------------------------------------
+ What is guacamole-auth-noauth?
+------------------------------------------------------------
+
+guacamole-auth-noauth is a Java library for use with the Guacamole web
+application which removes all authentication. It provides a static set of
+connections to anyone using the web application.
+
+Beware that with authentication disabled, any person with access to your
+Guacamole server will have access to any connections it provides. The login
+screen will not appear unless guacamole-auth-noauth was set up incorrectly or
+it is not compatible with your version of Guacamole.
+
+
+------------------------------------------------------------
+ Compiling and installing guacamole-auth-noauth
+------------------------------------------------------------
+
+guacamole-auth-noauth is built using Maven. Building guacamole-auth-noauth
+compiles all classes and packages them into a redistributable .jar file. This
+.jar file can be installed in the library directory configured in
+guacamole.properties such that the authentication provider is available.
+
+1) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .jar file will be
+    created in the target/ subdirectory of the current directory.
+
+    If this process fails, check the build errors, and verify that the
+    contents of your settings.xml file is correct.
+
+2) Extract the .tar.gz file now present in the target/ directory, and
+   place the .jar files in the extracted lib/ subdirectory in the library
+   directory specified in guacamole.properties.
+
+    You will likely need to do this as root.
+
+    If you do not have a library directory configured in your
+    guacamole.properties, you will need to specify one. The directory
+    is specified using the "lib-directory" property.
+
+3) Write a noauth-config.xml file containing all desired connections
+
+    The guacamole-auth-noauth authentication provided is configured by a
+    static XML file which lists all available connections.
+
+    The file consists of a single <configs> tag which contains any number of
+    <config> tags, each having a name and protocol. These <config> tags
+    correspond to connections.
+
+    Each <config> can contain any number of <param> tags which correspond to
+    the parameters of the protocol chosen. Each <param> tag has a name and
+    value, where the name is defined by the documentation of the protocol
+    being used.
+
+    For example, to define a single RDP connection to your RDP server with
+    the hostname "my-rdp-server-hostname", you could write:
+
+    <configs>
+      <config name="my-rdp-server" protocol="rdp">
+        <param name="hostname" value="my-rdp-server-hostname" />
+        <param name="port" value="3389" />
+      </config>
+    </configs>
+
+    When completed, this file should be placed in a common location such
+    that it can be referenced from guacamole.properties, like
+    /etc/guacamole/noauth-config.xml.
+
+4) Configure guacamole.properties
+
+    An additional property is required by guacamole-auth-noauth which defines
+    where the configuration file is found. It must be added to your
+    guacamole.properties:
+
+    # Configuration for NoAuth
+    noauth-config: /etc/guacamole/noauth-config.xml
+
+5) Restart Tomcat
+
+    The guacamole.properties file as well as any authentication provider .jar
+    files are only read when Tomcat starts. This goes for any other servlet
+    container as well.
+
+    You must restart Tomcat before any of the above changes can take effect.

+     claims:
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Initial Developer to use, reproduce,
+          modify, display, perform, sublicense and distribute the Original
+          Code (or portions thereof) with or without Modifications, and/or
+          as part of a Larger Work; and
+
+          (b) under Patents Claims infringed by the making, using or
+          selling of Original Code, to make, have made, use, practice,
+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+
+          (c) the licenses granted in this Section 2.1(a) and (b) are
+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license is
+          granted: 1) for code that You delete from the Original Code; 2)
+          separate from the Original Code;  or 3) for infringements caused
+          by: i) the modification of the Original Code or ii) the
+          combination of the Original Code with other software or devices.

+
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Contributor, to use, reproduce, modify,
+          display, perform, sublicense and distribute the Modifications
+          created by such Contributor (or portions thereof) either on an
+          unmodified basis, with other Modifications, as Covered Code
+          and/or as part of a Larger Work; and
+
+          (b) under Patent Claims infringed by the making, using, or
+          selling of  Modifications made by that Contributor either alone
+          and/or in combination with its Contributor Version (or portions
+          of such combination), to make, use, sell, offer for sale, have
+          made, and/or otherwise dispose of: 1) Modifications made by that
+          Contributor (or portions thereof); and 2) the combination of
+          Modifications made by that Contributor with its Contributor
+          Version (or portions of such combination).
+
+          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
+          effective on the date Contributor first makes Commercial Use of
+          the Covered Code.
+
+          (d)    Notwithstanding Section 2.2(b) above, no patent license is
+          granted: 1) for any code that Contributor has deleted from the

+          infringed by Covered Code in the absence of Modifications made by
+          that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.
+     The Modifications which You create or to which You contribute are
+     governed by the terms of this License, including without limitation
+     Section 2.2. The Source Code version of Covered Code may be
+     distributed only under the terms of this License or a future version
+     of this License released under Section 6.1, and You must include a
+     copy of this License with every copy of the Source Code You
+     distribute. You may not offer or impose any terms on any Source Code
+     version that alters or restricts the applicable version of this
+     License or the recipients' rights hereunder. However, You may include
+     an additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.
+     Any Modification which You create or to which You contribute must be
+     made available in Source Code form under the terms of this License
+     either on the same media as an Executable version or via an accepted
+     Electronic Distribution Mechanism to anyone to whom you made an
+     Executable version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve (12)
+     months after the date it initially became available, or at least six
+     (6) months after a subsequent version of that particular Modification
+     has been made available to such recipients. You are responsible for
+     ensuring that the Source Code version remains available even if the
+     Electronic Distribution Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.
+     You must cause all Covered Code to which You contribute to contain a
+     file documenting the changes You made to create that Covered Code and
+     the date of any change. You must include a prominent statement that
+     the Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of the
+     Initial Developer in (a) the Source Code, and (b) in any notice in an
+     Executable version or related documentation in which You describe the
+     origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters
+          (a) Third Party Claims.
+          If Contributor has knowledge that a license under a third party's
+          intellectual property rights is required to exercise the rights
+          granted by such Contributor under Sections 2.1 or 2.2,
+          Contributor must include a text file with the Source Code
+          distribution titled "LEGAL" which describes the claim and the
+          party making the claim in sufficient detail that a recipient will
+          know whom to contact. If Contributor obtains such knowledge after
+          the Modification is made available as described in Section 3.2,
+          Contributor shall promptly modify the LEGAL file in all copies
+          Contributor makes available thereafter and shall take other steps
+          (such as notifying appropriate mailing lists or newsgroups)
+          reasonably calculated to inform those who received the Covered
+          Code that new knowledge has been obtained.
+
+          (b) Contributor APIs.
+          If Contributor's Modifications include an application programming
+          interface and Contributor has knowledge of patent licenses which
+          are reasonably necessary to implement that API, Contributor must
+          also include this information in the LEGAL file.
+
+               (c)    Representations.
+          Contributor represents that, except as disclosed pursuant to
+          Section 3.4(a) above, Contributor believes that Contributor's
+          Modifications are Contributor's original creation(s) and/or
+          Contributor has sufficient rights to grant the rights conveyed by
+          this License.
+
+     3.5. Required Notices.
+     You must duplicate the notice in Exhibit A in each file of the Source
+     Code.  If it is not possible to put such notice in a particular Source
+     Code file due to its structure, then You must include such notice in a
+     location (such as a relevant directory) where a user would be likely
+     to look for such a notice.  If You created one or more Modification(s)
+     You may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any documentation
+     for the Source Code where You describe recipients' rights or ownership
+     rights relating to Covered Code.  You may choose to offer, and to
+     charge a fee for, warranty, support, indemnity or liability
+     obligations to one or more recipients of Covered Code. However, You
+     may do so only on Your own behalf, and not on behalf of the Initial
+     Developer or any Contributor. You must make it absolutely clear than
+     any such warranty, support, indemnity or liability obligation is
+     offered by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.
+     You may distribute Covered Code in Executable form only if the
+     requirements of Section 3.1-3.5 have been met for that Covered Code,
+     and if You include a notice stating that the Source Code version of
+     the Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously included
+     in any notice in an Executable version, related documentation or
+     collateral in which You describe recipients' rights relating to the
+     Covered Code. You may distribute the Executable version of Covered
+     Code or ownership rights under a license of Your choice, which may
+     contain terms different from this License, provided that You are in
+     compliance with the terms of this License and that the license for the
+     Executable version does not attempt to limit or alter the recipient's
+     rights in the Source Code version from the rights set forth in this
+     License. If You distribute the Executable version under a different
+     license You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability incurred by
+     the Initial Developer or such Contributor as a result of any such
+     terms You offer.
+
+     3.7. Larger Works.
+     You may create a Larger Work by combining Covered Code with other code
+     not governed by the terms of this License and distribute the Larger
+     Work as a single product. In such a case, You must make sure the
+     requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of this
+     License with respect to some or all of the Covered Code due to
+     statute, judicial order, or regulation then You must: (a) comply with
+     the terms of this License to the maximum extent possible; and (b)
+     describe the limitations and the code they affect. Such description
+     must be included in the LEGAL file described in Section 3.4 and must
+     be included with all distributions of the Source Code. Except to the
+     extent prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be able to
+     understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.
+     Netscape Communications Corporation ("Netscape") may publish revised
+     and/or new versions of the License from time to time. Each version
+     will be given a distinguishing version number.
+
+     6.2. Effect of New Versions.
+     Once Covered Code has been published under a particular version of the
+     License, You may always continue to use it under the terms of that
+     version. You may also choose to use such Covered Code under the terms
+     of any subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable to
+     Covered Code created under this License.
+
+     6.3. Derivative Works.
+     If You create or use a modified version of this License (which you may
+     only do in order to apply it to code which is not already Covered Code
+     governed by this License), You must (a) rename Your license so that
+     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+     "MPL", "NPL" or any confusingly similar phrase do not appear in your
+     license (except to note that your license differs from this License)
+     and (b) otherwise make it clear that Your version of the license
+     contains terms which differ from the Mozilla Public License and
+     Netscape Public License. (Filling in the name of the Initial
+     Developer, Original Code or Contributor in the notice described in
+     Exhibit A shall not of themselves be deemed to be modifications of
+     this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will terminate
+     automatically if You fail to comply with terms herein and fail to cure
+     such breach within 30 days of becoming aware of the breach. All
+     sublicenses to the Covered Code which are properly granted shall
+     survive any termination of this License. Provisions which, by their
+     nature, must remain in effect beyond the termination of this License
+     shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent infringement
+     claim (excluding declatory judgment actions) against Initial Developer
+     or a Contributor (the Initial Developer or Contributor against whom
+     You file such action is referred to as "Participant")  alleging that:
+
+     (a)  such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate prospectively,
+     unless if within 60 days after receipt of notice You either: (i)
+     agree in writing to pay Participant a mutually agreeable reasonable
+     royalty for Your past and future use of Modifications made by such
+     Participant, or (ii) withdraw Your litigation claim with respect to
+     the Contributor Version against such Participant.  If within 60 days
+     of notice, a reasonable royalty and payment arrangement are not
+     mutually agreed upon in writing by the parties or the litigation claim
+     is not withdrawn, the rights granted by Participant to You under
+     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+     the 60 day notice period specified above.
+
+     (b)  any software, hardware, or device, other than such Participant's
+     Contributor Version, directly or indirectly infringes any patent, then
+     any rights granted to You by such Participant under Sections 2.1(b)
+     and 2.2(b) are revoked effective as of the date You first made, used,
+     sold, distributed, or had made, Modifications made by that
+     Participant.
+
+     8.3.  If You assert a patent infringement claim against Participant
+     alleging that such Participant's Contributor Version directly or
+     indirectly infringes any patent where such claim is resolved (such as
+     by license or settlement) prior to the initiation of patent
+     infringement litigation, then the reasonable value of the licenses
+     granted by such Participant under Sections 2.1 or 2.2 shall be taken
+     into account in determining the amount or value of any payment or
+     license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
+     all end user license agreements (excluding distributors and resellers)
+     which have been validly granted by You or any distributor hereunder
+     prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
+     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
+     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+     The Covered Code is a "commercial item," as that term is defined in
+     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+     software" and "commercial computer software documentation," as such
+     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
+     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
+     all U.S. Government End Users acquire Covered Code with only those
+     rights set forth herein.
+
+11. MISCELLANEOUS.
+
+     This License represents the complete agreement concerning subject
+     matter hereof. If any provision of this License is held to be
+     unenforceable, such provision shall be reformed only to the extent
+     necessary to make it enforceable. This License shall be governed by
+     California law provisions (except to the extent applicable law, if
+     any, provides otherwise), excluding its conflict-of-law provisions.
+     With respect to disputes in which at least one party is a citizen of,
+     or an entity chartered or registered to do business in the United
+     States of America, any litigation relating to this License shall be
+     subject to the jurisdiction of the Federal Courts of the Northern
+     District of California, with venue lying in Santa Clara County,
+     California, with the losing party responsible for costs, including
+     without limitation, court costs and reasonable attorneys' fees and
+     expenses. The application of the United Nations Convention on
+     Contracts for the International Sale of Goods is expressly excluded.
+     Any law or regulation which provides that the language of a contract
+     shall be construed against the drafter shall not apply to this
+     License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+     As between Initial Developer and the Contributors, each party is
+     responsible for claims and damages arising, directly or indirectly,
+     out of its utilization of rights under this License and You agree to
+     work with Initial Developer and Contributors to distribute such
+     responsibility on an equitable basis. Nothing herein is intended or
+     shall be deemed to constitute any admission of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+     Initial Developer may designate portions of the Covered Code as
+     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial
+     Developer permits you to utilize portions of the Covered Code under
+     Your choice of the NPL or the alternative licenses, if any, specified
+     by the Initial Developer in the file described in Exhibit A.

+ What is guacamole-common-js?
+------------------------------------------------------------
+
+guacamole-common-js is the core JavaScript library used by the Guacamole web
+application.
+
+guacamole-common-js provides an efficient HTTP tunnel for transporting
+protocol data between JavaScript and the web application, as well as an
+implementation of a Guacamole protocol client and abstract synchronized
+drawing layers. 
+
+
+------------------------------------------------------------
+ Compiling and installing guacamole-common-js
+------------------------------------------------------------
+
+guacamole-common-js is built using Maven. Note that this is JavaScript code
+and not actually compiled. "Building" guacamole-common-js actually simply
+packages it into a redistributable .zip file. This .zip file can be easily
+included and expanded into other Maven-based projects (like Guacamole).
+
+Note that prebuilt versions of guacamole-common-js are available from the
+main guac-dev.org Maven repository which is referenced in all Maven
+projects in Guacamole. Unless you want to make changes to guacamole-common-js
+or you want to use a newer, unreleased version (such as the unstable branch),
+you do not need to build this manually. You can let Maven download it for
+you when you build Guacamole.
+
+1) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .zip file.
+    Once all dependencies have been downloaded, the .zip file will be
+    created in the target/ subdirectory of the current directory.
+
+2) Run mvn install
+
+    $ mvn install
+
+    DO NOT RUN THIS AS ROOT!
+
+    Maven will install guacamole-common-js to your user's local Maven
+    repository where it can be used in future builds. It will not install
+    into a system-wide repository and does not require root privileges.
+
+    Once installed, building other Maven projects that depend on
+    guacamole-common-js (such as Guacamole) will be possible.

+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+

+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license is
+          granted: 1) for code that You delete from the Original Code; 2)

+          of such combination), to make, use, sell, offer for sale, have
+          made, and/or otherwise dispose of: 1) Modifications made by that
+          Contributor (or portions thereof); and 2) the combination of

+          infringed by Covered Code in the absence of Modifications made by
+          that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.
+     The Modifications which You create or to which You contribute are
+     governed by the terms of this License, including without limitation
+     Section 2.2. The Source Code version of Covered Code may be
+     distributed only under the terms of this License or a future version
+     of this License released under Section 6.1, and You must include a
+     copy of this License with every copy of the Source Code You
+     distribute. You may not offer or impose any terms on any Source Code
+     version that alters or restricts the applicable version of this
+     License or the recipients' rights hereunder. However, You may include
+     an additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.
+     Any Modification which You create or to which You contribute must be
+     made available in Source Code form under the terms of this License
+     either on the same media as an Executable version or via an accepted
+     Electronic Distribution Mechanism to anyone to whom you made an
+     Executable version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve (12)
+     months after the date it initially became available, or at least six
+     (6) months after a subsequent version of that particular Modification
+     has been made available to such recipients. You are responsible for
+     ensuring that the Source Code version remains available even if the
+     Electronic Distribution Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.
+     You must cause all Covered Code to which You contribute to contain a
+     file documenting the changes You made to create that Covered Code and
+     the date of any change. You must include a prominent statement that
+     the Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of the
+     Initial Developer in (a) the Source Code, and (b) in any notice in an
+     Executable version or related documentation in which You describe the
+     origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters
+          (a) Third Party Claims.
+          If Contributor has knowledge that a license under a third party's
+          intellectual property rights is required to exercise the rights
+          granted by such Contributor under Sections 2.1 or 2.2,
+          Contributor must include a text file with the Source Code
+          distribution titled "LEGAL" which describes the claim and the
+          party making the claim in sufficient detail that a recipient will
+          know whom to contact. If Contributor obtains such knowledge after
+          the Modification is made available as described in Section 3.2,
+          Contributor shall promptly modify the LEGAL file in all copies
+          Contributor makes available thereafter and shall take other steps
+          (such as notifying appropriate mailing lists or newsgroups)
+          reasonably calculated to inform those who received the Covered
+          Code that new knowledge has been obtained.
+
+          (b) Contributor APIs.
+          If Contributor's Modifications include an application programming
+          interface and Contributor has knowledge of patent licenses which
+          are reasonably necessary to implement that API, Contributor must
+          also include this information in the LEGAL file.
+
+               (c)    Representations.
+          Contributor represents that, except as disclosed pursuant to
+          Section 3.4(a) above, Contributor believes that Contributor's
+          Modifications are Contributor's original creation(s) and/or
+          Contributor has sufficient rights to grant the rights conveyed by
+          this License.
+
+     3.5. Required Notices.
+     You must duplicate the notice in Exhibit A in each file of the Source
+     Code.  If it is not possible to put such notice in a particular Source
+     Code file due to its structure, then You must include such notice in a
+     location (such as a relevant directory) where a user would be likely
+     to look for such a notice.  If You created one or more Modification(s)
+     You may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any documentation
+     for the Source Code where You describe recipients' rights or ownership
+     rights relating to Covered Code.  You may choose to offer, and to
+     charge a fee for, warranty, support, indemnity or liability
+     obligations to one or more recipients of Covered Code. However, You
+     may do so only on Your own behalf, and not on behalf of the Initial
+     Developer or any Contributor. You must make it absolutely clear than
+     any such warranty, support, indemnity or liability obligation is
+     offered by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.
+     You may distribute Covered Code in Executable form only if the
+     requirements of Section 3.1-3.5 have been met for that Covered Code,
+     and if You include a notice stating that the Source Code version of
+     the Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously included
+     in any notice in an Executable version, related documentation or
+     collateral in which You describe recipients' rights relating to the
+     Covered Code. You may distribute the Executable version of Covered
+     Code or ownership rights under a license of Your choice, which may
+     contain terms different from this License, provided that You are in
+     compliance with the terms of this License and that the license for the
+     Executable version does not attempt to limit or alter the recipient's
+     rights in the Source Code version from the rights set forth in this
+     License. If You distribute the Executable version under a different
+     license You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability incurred by
+     the Initial Developer or such Contributor as a result of any such
+     terms You offer.
+
+     3.7. Larger Works.
+     You may create a Larger Work by combining Covered Code with other code
+     not governed by the terms of this License and distribute the Larger
+     Work as a single product. In such a case, You must make sure the
+     requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of this
+     License with respect to some or all of the Covered Code due to
+     statute, judicial order, or regulation then You must: (a) comply with
+     the terms of this License to the maximum extent possible; and (b)
+     describe the limitations and the code they affect. Such description
+     must be included in the LEGAL file described in Section 3.4 and must
+     be included with all distributions of the Source Code. Except to the
+     extent prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be able to
+     understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.
+     Netscape Communications Corporation ("Netscape") may publish revised
+     and/or new versions of the License from time to time. Each version
+     will be given a distinguishing version number.
+
+     6.2. Effect of New Versions.
+     Once Covered Code has been published under a particular version of the
+     License, You may always continue to use it under the terms of that
+     version. You may also choose to use such Covered Code under the terms
+     of any subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable to
+     Covered Code created under this License.
+
+     6.3. Derivative Works.
+     If You create or use a modified version of this License (which you may
+     only do in order to apply it to code which is not already Covered Code
+     governed by this License), You must (a) rename Your license so that
+     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+     "MPL", "NPL" or any confusingly similar phrase do not appear in your
+     license (except to note that your license differs from this License)
+     and (b) otherwise make it clear that Your version of the license
+     contains terms which differ from the Mozilla Public License and
+     Netscape Public License. (Filling in the name of the Initial
+     Developer, Original Code or Contributor in the notice described in
+     Exhibit A shall not of themselves be deemed to be modifications of
+     this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will terminate
+     automatically if You fail to comply with terms herein and fail to cure
+     such breach within 30 days of becoming aware of the breach. All
+     sublicenses to the Covered Code which are properly granted shall
+     survive any termination of this License. Provisions which, by their
+     nature, must remain in effect beyond the termination of this License
+     shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent infringement
+     claim (excluding declatory judgment actions) against Initial Developer
+     or a Contributor (the Initial Developer or Contributor against whom
+     You file such action is referred to as "Participant")  alleging that:
+
+     (a)  such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate prospectively,
+     unless if within 60 days after receipt of notice You either: (i)
+     agree in writing to pay Participant a mutually agreeable reasonable
+     royalty for Your past and future use of Modifications made by such
+     Participant, or (ii) withdraw Your litigation claim with respect to
+     the Contributor Version against such Participant.  If within 60 days
+     of notice, a reasonable royalty and payment arrangement are not
+     mutually agreed upon in writing by the parties or the litigation claim
+     is not withdrawn, the rights granted by Participant to You under
+     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+     the 60 day notice period specified above.
+
+     (b)  any software, hardware, or device, other than such Participant's
+     Contributor Version, directly or indirectly infringes any patent, then
+     any rights granted to You by such Participant under Sections 2.1(b)
+     and 2.2(b) are revoked effective as of the date You first made, used,
+     sold, distributed, or had made, Modifications made by that
+     Participant.
+
+     8.3.  If You assert a patent infringement claim against Participant
+     alleging that such Participant's Contributor Version directly or
+     indirectly infringes any patent where such claim is resolved (such as
+     by license or settlement) prior to the initiation of patent
+     infringement litigation, then the reasonable value of the licenses
+     granted by such Participant under Sections 2.1 or 2.2 shall be taken
+     into account in determining the amount or value of any payment or
+     license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
+     all end user license agreements (excluding distributors and resellers)
+     which have been validly granted by You or any distributor hereunder
+     prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
+     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
+     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+     The Covered Code is a "commercial item," as that term is defined in
+     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+     software" and "commercial computer software documentation," as such
+     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
+     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
+     all U.S. Government End Users acquire Covered Code with only those
+     rights set forth herein.
+
+11. MISCELLANEOUS.
+
+     This License represents the complete agreement concerning subject
+     matter hereof. If any provision of this License is held to be
+     unenforceable, such provision shall be reformed only to the extent
+     necessary to make it enforceable. This License shall be governed by
+     California law provisions (except to the extent applicable law, if
+     any, provides otherwise), excluding its conflict-of-law provisions.
+     With respect to disputes in which at least one party is a citizen of,
+     or an entity chartered or registered to do business in the United
+     States of America, any litigation relating to this License shall be
+     subject to the jurisdiction of the Federal Courts of the Northern
+     District of California, with venue lying in Santa Clara County,
+     California, with the losing party responsible for costs, including
+     without limitation, court costs and reasonable attorneys' fees and
+     expenses. The application of the United Nations Convention on
+     Contracts for the International Sale of Goods is expressly excluded.
+     Any law or regulation which provides that the language of a contract
+     shall be construed against the drafter shall not apply to this
+     License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+     As between Initial Developer and the Contributors, each party is
+     responsible for claims and damages arising, directly or indirectly,
+     out of its utilization of rights under this License and You agree to
+     work with Initial Developer and Contributors to distribute such
+     responsibility on an equitable basis. Nothing herein is intended or
+     shall be deemed to constitute any admission of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+     Initial Developer may designate portions of the Covered Code as
+     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial
+     Developer permits you to utilize portions of the Covered Code under
+     Your choice of the NPL or the alternative licenses, if any, specified
+     by the Initial Developer in the file described in Exhibit A.

+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+ 
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:
+
+    http://guac-dev.org/

+
+------------------------------------------------------------
+ What is guacamole-common?
+------------------------------------------------------------
+
+guacamole-common is the core Java library used by the Guacamole web
+application.
+
+guacamole-common provides abstract means of connecting to guacd, interfacing
+with the JavaScript client and tunnel provided by guacamole-common-js, and
+reading configuration from a standard location (guacamole.properties).
+
+
+------------------------------------------------------------
+ Compiling and installing guacamole-common
+------------------------------------------------------------
+
+guacamole-common is built using Maven. Building guacamole-common
+compiles all classes and packages them into a redistributable .jar file. This
+.jar file can be easily included in other Maven-based projects (like Guacamole).
+
+Note that prebuilt versions of guacamole-common are available from the
+main guac-dev.org Maven repository which is referenced in all Maven
+projects in Guacamole. Unless you want to make changes to guacamole-common
+or you want to use a newer, unreleased version (such as the unstable branch),
+you do not need to build this manually. You can let Maven download it for
+you when you build Guacamole.
+
+1) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .jar file will be
+    created in the target/ subdirectory of the current directory.
+
+2) Run mvn install
+
+    $ mvn install
+
+    DO NOT RUN THIS AS ROOT!
+
+    Maven will install guacamole-common to your user's local Maven
+    repository where it can be used in future builds. It will not install
+    into a system-wide repository and does not require root privileges.
+
+    Once installed, building other Maven projects that depend on
+    guacamole-common (such as Guacamole) will be possible.
+

+     The Initial Developer hereby grants You a world-wide, royalty-free,
+     non-exclusive license, subject to third party intellectual property
+     claims:
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Initial Developer to use, reproduce,
+          modify, display, perform, sublicense and distribute the Original
+          Code (or portions thereof) with or without Modifications, and/or
+          as part of a Larger Work; and
+
+          (b) under Patents Claims infringed by the making, using or
+          selling of Original Code, to make, have made, use, practice,
+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+
+          (c) the licenses granted in this Section 2.1(a) and (b) are
+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license is
+          granted: 1) for code that You delete from the Original Code; 2)
+          separate from the Original Code;  or 3) for infringements caused
+          by: i) the modification of the Original Code or ii) the
+          combination of the Original Code with other software or devices.
+
+     2.2. Contributor Grant.
+     Subject to third party intellectual property claims, each Contributor
+     hereby grants You a world-wide, royalty-free, non-exclusive license
+
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Contributor, to use, reproduce, modify,
+          display, perform, sublicense and distribute the Modifications
+          created by such Contributor (or portions thereof) either on an
+          unmodified basis, with other Modifications, as Covered Code
+          and/or as part of a Larger Work; and
+
+          (b) under Patent Claims infringed by the making, using, or
+          selling of  Modifications made by that Contributor either alone
+          and/or in combination with its Contributor Version (or portions
+          of such combination), to make, use, sell, offer for sale, have
+          made, and/or otherwise dispose of: 1) Modifications made by that
+          Contributor (or portions thereof); and 2) the combination of
+          Modifications made by that Contributor with its Contributor
+          Version (or portions of such combination).
+
+          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
+          effective on the date Contributor first makes Commercial Use of
+          the Covered Code.
+
+          (d)    Notwithstanding Section 2.2(b) above, no patent license is
+          granted: 1) for any code that Contributor has deleted from the
+          Contributor Version; 2)  separate from the Contributor Version;
+          3)  for infringements caused by: i) third party modifications of
+          Contributor Version or ii)  the combination of Modifications made
+          by that Contributor with other software  (except as part of the
+          Contributor Version) or other devices; or 4) under Patent Claims
+          infringed by Covered Code in the absence of Modifications made by
+          that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.
+     The Modifications which You create or to which You contribute are
+     governed by the terms of this License, including without limitation
+     Section 2.2. The Source Code version of Covered Code may be
+     distributed only under the terms of this License or a future version
+     of this License released under Section 6.1, and You must include a
+     copy of this License with every copy of the Source Code You
+     distribute. You may not offer or impose any terms on any Source Code
+     version that alters or restricts the applicable version of this
+     License or the recipients' rights hereunder. However, You may include
+     an additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.
+     Any Modification which You create or to which You contribute must be
+     made available in Source Code form under the terms of this License
+     either on the same media as an Executable version or via an accepted
+     Electronic Distribution Mechanism to anyone to whom you made an
+     Executable version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve (12)
+     months after the date it initially became available, or at least six
+     (6) months after a subsequent version of that particular Modification
+     has been made available to such recipients. You are responsible for
+     ensuring that the Source Code version remains available even if the
+     Electronic Distribution Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.
+     You must cause all Covered Code to which You contribute to contain a
+     file documenting the changes You made to create that Covered Code and
+     the date of any change. You must include a prominent statement that
+     the Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of the
+     Initial Developer in (a) the Source Code, and (b) in any notice in an
+     Executable version or related documentation in which You describe the
+     origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters
+          (a) Third Party Claims.
+          If Contributor has knowledge that a license under a third party's
+          intellectual property rights is required to exercise the rights
+          granted by such Contributor under Sections 2.1 or 2.2,
+          Contributor must include a text file with the Source Code
+          distribution titled "LEGAL" which describes the claim and the
+          party making the claim in sufficient detail that a recipient will
+          know whom to contact. If Contributor obtains such knowledge after
+          the Modification is made available as described in Section 3.2,
+          Contributor shall promptly modify the LEGAL file in all copies
+          Contributor makes available thereafter and shall take other steps
+          (such as notifying appropriate mailing lists or newsgroups)
+          reasonably calculated to inform those who received the Covered
+          Code that new knowledge has been obtained.
+
+          (b) Contributor APIs.
+          If Contributor's Modifications include an application programming
+          interface and Contributor has knowledge of patent licenses which
+          are reasonably necessary to implement that API, Contributor must
+          also include this information in the LEGAL file.
+
+               (c)    Representations.
+          Contributor represents that, except as disclosed pursuant to
+          Section 3.4(a) above, Contributor believes that Contributor's
+          Modifications are Contributor's original creation(s) and/or
+          Contributor has sufficient rights to grant the rights conveyed by
+          this License.
+
+     3.5. Required Notices.
+     You must duplicate the notice in Exhibit A in each file of the Source
+     Code.  If it is not possible to put such notice in a particular Source
+     Code file due to its structure, then You must include such notice in a
+     location (such as a relevant directory) where a user would be likely
+     to look for such a notice.  If You created one or more Modification(s)
+     You may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any documentation
+     for the Source Code where You describe recipients' rights or ownership
+     rights relating to Covered Code.  You may choose to offer, and to
+     charge a fee for, warranty, support, indemnity or liability
+     obligations to one or more recipients of Covered Code. However, You
+     may do so only on Your own behalf, and not on behalf of the Initial
+     Developer or any Contributor. You must make it absolutely clear than
+     any such warranty, support, indemnity or liability obligation is
+     offered by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.
+     You may distribute Covered Code in Executable form only if the
+     requirements of Section 3.1-3.5 have been met for that Covered Code,
+     and if You include a notice stating that the Source Code version of
+     the Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously included
+     in any notice in an Executable version, related documentation or
+     collateral in which You describe recipients' rights relating to the
+     Covered Code. You may distribute the Executable version of Covered
+     Code or ownership rights under a license of Your choice, which may
+     contain terms different from this License, provided that You are in
+     compliance with the terms of this License and that the license for the
+     Executable version does not attempt to limit or alter the recipient's
+     rights in the Source Code version from the rights set forth in this
+     License. If You distribute the Executable version under a different
+     license You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability incurred by
+     the Initial Developer or such Contributor as a result of any such
+     terms You offer.
+
+     3.7. Larger Works.
+     You may create a Larger Work by combining Covered Code with other code
+     not governed by the terms of this License and distribute the Larger
+     Work as a single product. In such a case, You must make sure the
+     requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of this
+     License with respect to some or all of the Covered Code due to
+     statute, judicial order, or regulation then You must: (a) comply with
+     the terms of this License to the maximum extent possible; and (b)
+     describe the limitations and the code they affect. Such description
+     must be included in the LEGAL file described in Section 3.4 and must
+     be included with all distributions of the Source Code. Except to the
+     extent prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be able to
+     understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.
+     Netscape Communications Corporation ("Netscape") may publish revised
+     and/or new versions of the License from time to time. Each version
+     will be given a distinguishing version number.
+
+     6.2. Effect of New Versions.
+     Once Covered Code has been published under a particular version of the
+     License, You may always continue to use it under the terms of that
+     version. You may also choose to use such Covered Code under the terms
+     of any subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable to
+     Covered Code created under this License.
+
+     6.3. Derivative Works.
+     If You create or use a modified version of this License (which you may
+     only do in order to apply it to code which is not already Covered Code
+     governed by this License), You must (a) rename Your license so that
+     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+     "MPL", "NPL" or any confusingly similar phrase do not appear in your
+     license (except to note that your license differs from this License)
+     and (b) otherwise make it clear that Your version of the license
+     contains terms which differ from the Mozilla Public License and
+     Netscape Public License. (Filling in the name of the Initial
+     Developer, Original Code or Contributor in the notice described in
+     Exhibit A shall not of themselves be deemed to be modifications of
+     this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will terminate
+     automatically if You fail to comply with terms herein and fail to cure
+     such breach within 30 days of becoming aware of the breach. All
+     sublicenses to the Covered Code which are properly granted shall
+     survive any termination of this License. Provisions which, by their
+     nature, must remain in effect beyond the termination of this License
+     shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent infringement
+     claim (excluding declatory judgment actions) against Initial Developer
+     or a Contributor (the Initial Developer or Contributor against whom
+     You file such action is referred to as "Participant")  alleging that:
+
+     (a)  such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate prospectively,
+     unless if within 60 days after receipt of notice You either: (i)
+     agree in writing to pay Participant a mutually agreeable reasonable
+     royalty for Your past and future use of Modifications made by such
+     Participant, or (ii) withdraw Your litigation claim with respect to
+     the Contributor Version against such Participant.  If within 60 days
+     of notice, a reasonable royalty and payment arrangement are not
+     mutually agreed upon in writing by the parties or the litigation claim
+     is not withdrawn, the rights granted by Participant to You under
+     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+     the 60 day notice period specified above.
+
+     (b)  any software, hardware, or device, other than such Participant's
+     Contributor Version, directly or indirectly infringes any patent, then
+     any rights granted to You by such Participant under Sections 2.1(b)
+     and 2.2(b) are revoked effective as of the date You first made, used,
+     sold, distributed, or had made, Modifications made by that
+     Participant.
+
+     8.3.  If You assert a patent infringement claim against Participant
+     alleging that such Participant's Contributor Version directly or
+     indirectly infringes any patent where such claim is resolved (such as
+     by license or settlement) prior to the initiation of patent
+     infringement litigation, then the reasonable value of the licenses
+     granted by such Participant under Sections 2.1 or 2.2 shall be taken
+     into account in determining the amount or value of any payment or
+     license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
+     all end user license agreements (excluding distributors and resellers)
+     which have been validly granted by You or any distributor hereunder
+     prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
+     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
+     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+     The Covered Code is a "commercial item," as that term is defined in
+     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+     software" and "commercial computer software documentation," as such
+     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
+     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
+     all U.S. Government End Users acquire Covered Code with only those
+     rights set forth herein.
+
+11. MISCELLANEOUS.
+
+     This License represents the complete agreement concerning subject
+     matter hereof. If any provision of this License is held to be
+     unenforceable, such provision shall be reformed only to the extent
+     necessary to make it enforceable. This License shall be governed by
+     California law provisions (except to the extent applicable law, if
+     any, provides otherwise), excluding its conflict-of-law provisions.
+     With respect to disputes in which at least one party is a citizen of,
+     or an entity chartered or registered to do business in the United
+     States of America, any litigation relating to this License shall be
+     subject to the jurisdiction of the Federal Courts of the Northern
+     District of California, with venue lying in Santa Clara County,
+     California, with the losing party responsible for costs, including
+     without limitation, court costs and reasonable attorneys' fees and
+     expenses. The application of the United Nations Convention on

+------------------------------------------------------------
+ About this README
+------------------------------------------------------------
+
+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+ 
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:
+
+    http://guac-dev.org/
+
+
+------------------------------------------------------------
+ What is guacamole-common-auth?
+------------------------------------------------------------
+
+guacamole-common-auth is a Java library used by the Guacamole web
+application to allow its built-in authentication to be extended or
+modified and reused.
+
+guacamole-common-auth provides an interface for retrieving a set of
+authorized connection configurations for a given set of arbitrary
+credentials. Classes implementing this interface can be referenced in
+guacamole.properties to allow different authentication mechanisms
+(such as LDAP) to be used.
+
+
+------------------------------------------------------------
+ Compiling and installing guacamole-common-auth
+------------------------------------------------------------
+
+guacamole-common-auth is built using Maven. Building guacamole-common-auth
+compiles all classes and packages them into a redistributable .jar file. This
+.jar file can be easily included in other Maven-based projects (like Guacamole).
+
+Note that prebuilt versions of guacamole-common-auth are available from the
+main guac-dev.org Maven repository which is referenced in all Maven
+projects in Guacamole. Unless you want to make changes to guacamole-common-auth
+or you want to use a newer, unreleased version (such as the unstable branch),
+you do not need to build this manually. You can let Maven download it for
+you when you build Guacamole.
+
+1) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .jar file will be
+    created in the target/ subdirectory of the current directory.
+
+2) Run mvn install
+
+    $ mvn install
+
+    DO NOT RUN THIS AS ROOT!
+
+    Maven will install guacamole-common-auth to your user's local Maven
+    repository where it can be used in future builds. It will not install
+    into a system-wide repository and does not require root privileges.
+
+    Once installed, building other Maven projects that depend on
+    guacamole-common-auth (such as Guacamole) will be possible.
+

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+------------------------------------------------------------
+ About this README
+------------------------------------------------------------
+
+This README is intended to provide quick and to-the-point documentation for
+technical users intending to compile parts of Guacamole themselves.
+
+Distribution-specific packages are available from the files section of the main
+project page:
+ 
+    http://sourceforge.net/projects/guacamole/files/
+
+Distribution-specific documentation is provided on the Guacamole wiki:
+
+    http://guac-dev.org/
+
+
+------------------------------------------------------------
+ What is Guacamole?
+------------------------------------------------------------
+
+Guacamole is an HTML5 web application that provides access to your desktop using
+remote desktop protocols. A centralized server acts as a tunnel and proxy,
+allowing access to multiple desktops through a web browser; no plugins needed.
+The client requires nothing more than a web browser supporting HTML5 and AJAX.
+
+The Guacamole project maintains this web application and the Java and C
+libraries and programs it depends on. These libraries and programs are
+separate in order to enable others to implement other applications using the
+same underlying technology.
+
+All components and dependencies of Guacamole are free and open source.
+
+
+------------------------------------------------------------
+ Compiling and installing Guacamole
+------------------------------------------------------------
+
+Guacamole is built using Maven. Building Guacamole compiles all classes and
+packages them into a deployable .war file. This .war file can be installed
+and deployed under servlet containers like Apache Tomcat or Jetty.
+
+1) Run mvn package
+
+    $ mvn package
+
+    Maven will download any needed dependencies for building the .jar file.
+    Once all dependencies have been downloaded, the .war file will be
+    created in the target/ subdirectory of the current directory.
+
+2) Copy the .war file as directed in the instructions provided with
+   your servlet container.
+
+   Apache Tomcat, Jetty, and other servlet containers have specific and
+   varying locations that .war files must be placed for the web
+   application to be deployed.
+
+   You will likely need to do this as root.
+
+
+------------------------------------------------------------
+ Reporting problems

+
+Please report any bugs encountered by opening a new ticket at the Trac system
+hosted at:
+

+<h3 style="text-align: center;">GNU AFFERO GENERAL PUBLIC LICENSE</h3>
+<p style="text-align: center;">Version 3, 19 November 2007</p>
+
+<p>Copyright © 2007 Free Software Foundation,
+Inc. <<a href="http://fsf.org/">http://fsf.org/</a>>
+ <br />
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.</p>
+
+<h3><a name="preamble"></a>Preamble</h3>
+
+<p>The GNU Affero General Public License is a free, copyleft license
+for software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.</p>
+
+<p>The licenses for most software and other practical works are
+designed to take away your freedom to share and change the works.  By
+contrast, our General Public Licenses are intended to guarantee your
+freedom to share and change all versions of a program--to make sure it
+remains free software for all its users.</p>
+
+<p>When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.</p>
+
+<p>Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.</p>
+
+<p>A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.</p>
+
+<p>The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.</p>
+
+<p>An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.</p>
+
+<p>The precise terms and conditions for copying, distribution and
+modification follow.</p>
+
+<h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
+
+<h4><a name="section0"></a>0. Definitions.</h4>
+
+<p>"This License" refers to version 3 of the GNU Affero General Public
+License.</p>
+
+<p>"Copyright" also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.</p>
+
+<p>"The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.</p>
+
+<p>To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.</p>
+
+<p>A "covered work" means either the unmodified Program or a work based
+on the Program.</p>
+
+<p>To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.</p>
+
+<p>To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.</p>
+
+<p>An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.</p>
+
+<h4><a name="section1"></a>1. Source Code.</h4>
+
+<p>The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.</p>
+
+<p>A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.</p>
+
+<p>The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.</p>
+
+<p>The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.</p>
+
+<p>The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.</p>
+
+<p>The Corresponding Source for a work in source code form is that
+same work.</p>
+
+<h4><a name="section2"></a>2. Basic Permissions.</h4>
+
+<p>All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.</p>
+
+<p>You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.</p>
+
+<p>Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.</p>
+
+<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
+
+<p>No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.</p>
+
+<p>When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.</p>
+
+<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
+
+<p>You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.</p>
+
+<p>You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.</p>
+
+<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
+
+<p>You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:</p>
+
+<ul>
+
+<li>a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.</li>
+
+<li>b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".</li>
+
+<li>c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.</li>
+
+<li>d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.</li>
+
+</ul>
+
+<p>A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.</p>
+
+<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
+
+<p>You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:</p>
+
+<ul>
+
+<li>a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.</li>
+
+<li>b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.</li>
+
+<li>c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.</li>
+
+<li>d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.</li>
+
+<li>e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.</li>
+
+</ul>
+
+<p>A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.</p>
+
+<p>A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.</p>
+
+<p>"Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.</p>
+
+<p>If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).</p>
+
+<p>The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.</p>
+
+<p>Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.</p>
+
+<h4><a name="section7"></a>7. Additional Terms.</h4>
+
+<p>"Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.</p>
+
+<p>When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.</p>
+
+<p>Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:</p>
+
+<ul>
+
+<li>a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or</li>
+
+<li>b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or</li>
+
+<li>c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or</li>
+
+<li>d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or</li>
+
+<li>e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or</li>
+
+<li>f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.</li>
+
+</ul>
+
+<p>All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further restriction,
+you may remove that term.  If a license document contains a further
+restriction but permits relicensing or conveying under this License, you
+may add to a covered work material governed by the terms of that license
+document, provided that the further restriction does not survive such
+relicensing or conveying.</p>
+
+<p>If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.</p>
+
+<p>Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.</p>
+
+<h4><a name="section8"></a>8. Termination.</h4>
+
+<p>You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).</p>
+
+<p>However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.</p>
+
+<p>Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.</p>
+
+<p>Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.</p>
+
+<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
+
+<p>You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.</p>
+
+<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
+
+<p>Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.</p>
+
+<p>An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.</p>
+
+<p>You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.</p>
+
+<h4><a name="section11"></a>11. Patents.</h4>
+
+<p>A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".</p>
+
+<p>A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.</p>
+
+<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.</p>
+
+<p>In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.</p>
+
+<p>If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.</p>
+
+<p>If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.</p>
+
+<p>A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.</p>
+
+<p>Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.</p>
+
+<h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
+
+<p>If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.</p>
+
+<h4><a name="section13"></a>13. Remote Network Interaction; Use with the GNU General Public License.</h4>
+
+<p>Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.</p>
+
+<p>Notwithstanding any other provision of this License, you have permission
+to link or combine any covered work with a work licensed under version 3
+of the GNU General Public License into a single combined work, and to
+convey the resulting work.  The terms of this License will continue to
+apply to the part which is the covered work, but the work with which it is
+combined will remain governed by version 3 of the GNU General Public
+License.</p>
+
+<h4><a name="section14"></a>14. Revised Versions of this License.</h4>
+
+<p>The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new
+versions will be similar in spirit to the present version, but may differ
+in detail to address new problems or concerns.</p>
+
+<p>Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero
+General Public License "or any later version" applies to it, you have
+the option of following the terms and conditions either of that
+numbered version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number
+of the GNU Affero General Public License, you may choose any version
+ever published by the Free Software Foundation.</p>
+
+<p>If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that
+proxy's public statement of acceptance of a version permanently
+authorizes you to choose that version for the Program.</p>
+
+<p>Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.</p>
+
+<h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
+
+<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
+
+<h4><a name="section16"></a>16. Limitation of Liability.</h4>
+
+<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.</p>
+
+<h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
+
+<p>If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.</p>
+
+<p>END OF TERMS AND CONDITIONS</p>
+
+<h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
+
+<p>If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.</p>
+
+<p>To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.</p>
+
+<pre>    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as
+    published by the Free Software Foundation, either version 3 of the
+    License, or (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+</pre>
+
+<p>Also add information on how to contact you by electronic and paper mail.</p>
+
+<p>If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.</p>
+
+<p>You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<<a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>>.</p>
