+
+     Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+   Everyone is permitted to copy and distribute verbatim copies
+    of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  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
+this service 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.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+

+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+

+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+

+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+

+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE 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.
+
+                     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
+convey 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) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 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 General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+h5utils 1.9.1 (8/5/04)
+
+  * Fix h5topng compilation failure with some non-C99 compilers;
+    thanks to Maarten van Reeuwijk for the bug report.
+
+h5utils 1.9 (7/12/04)
+
+  * Added new h5math utility, which creates and combines HDF5 datasets
+    using a user-specified mathematical expression.  (Requires GNU
+    libmatheval to be installed.)
+
+  * h5topng: Matlab-like start:end or start:step:end notation for
+    slice indices, to allow a whole sequence of slices to be output as
+    a sequence of PNG images.
+
+  * h5topng: if contour/overlay dataset does not have same dimensions
+    as output data, it is periodically "tiled" over the output.
+
+h5utils 1.8 (5/22/04)
+
+  * New -A and -a options for h5topng to allow translucent overlays
+    from one file onto another (an alternative or complement to the
+    -C contour-overlay option).
+
+  * h5topng uses 24-bit direct color by default (use -8 option for
+    old 8-bit behavior).
+
+  * h5topng uses columns/rows for x/y by default (use -T to swap),
+    the opposite of the old behavior.
+
+  * There is no default -z 0 slice dimension in h5topng/h5totxt any more.
+    You must specify a slice for 3+ dimensional data in h5topng.
+    h5totxt dumps the whole data file by default unless one or more
+    slices are specified.
+
+  * Support specifying multiple slice dimensions for 4+ dimensional
+    datasets, with new "-t" option to indicate final dimension.
+
+  * Slices are also supported now in h5tovtk and h5tov5d.
+
+  * New -. option in h5totxt to specify number of significant digits; 
+    output 16 digits by default instead of 6, previously.
+
+h5utils 1.7.1 (3/16/02)
+
+  * Fixed array overrun in h5topng that caused a floating-point exception
+    on Alphas; thanks to Marin Soljacic for the bug report.
+
+h5utils 1.7 (3/9/02)
+
+  * h5topng now supports multiple, user-definable color tables, a number
+    of which are provided.  INCOMPATIBLE CHANGE: the -c option now has
+    the syntax: -c <colortable>.  The old behavior corresponds to the
+    included "bluered" colortable, invoked via: -c bluered.
+
+  * New -R option for h5topng to use a consistent color scale for
+    all specified files.
+
+  * New -0 option for h5topng and h5totxt that shifts the origin of the
+    slice coordinates to the dataset center.
+
+  * Added h5tovtk program to output VTK (Visualization ToolKit) data files.
+
+  * Support -T (transpose dimensions) option in h5tov5d.
+
+  * Fixed bug in h5topng that caused extra rows/columns of garbage pixels
+    to be written at the edges of images when scaling was used.
+
+  * When compiling the h5read Octave plugin, respect the CPPFLAGS and LDFLAGS 
+    environment variables.  Thanks to Max Colice for the bug report.
+
+  * Fixed problem when --without-h5tov5d and --without-h5fromh4 are used. 
+    Thanks to Nikola Ivanov Nikolov for the fix.
+
+h5utils 1.6 (1/17/01)
+
+  * Don't build h5fromh4 if the superior h4toh5 tool (from HDF5 1.4)
+    is present.  Also added --{with,without}-h5fromh4 option to
+    configure to force whether h5fromh4 is built.
+
+h5utils 1.5.1 (12/9/00)
+
+  * Support manually disabling Octave plugin support
+    (configure --without-octave) in case of C++ problems.
+
+  * Support Vis5d+ and Debian HDF header file locations.
+
+h5utils 1.5 (7/9/00)
+
+  * Added h5fromh4 program to convert HDF4 datasets to HDF5 format.
+
+  * Added -S <s> option to h5topng as a shortcut for -X <s> -Y <s>.
+
+h5utils 1.4 (5/28/00)
+
+  * Added h5fromtxt program to convert text input to an HDF5 dataset.
+
+h5utils 1.3.4 (1/31/00)
+
+  * Improved -C contour plotting in h5topng.
+
+  * Fix in h5topng man page (thanks to Christoph Becher).
+
+h5utils 1.3.3 (1/30/00)
+
+  * Bug fix in h5topng (would sometimes output solid black images).
+    Thanks to Karl Koch for the bug report.
+
+h5utils 1.3.2 (1/28/00)
+
+  * Added h5topng -Z option to center color scale on zero.
+
+  * Now support h5topng -C filename:dataset.
+
+h5utils 1.3.1 (1/27/00)
+
+  * Bug fixes in dataset name-handling, especially when using h5tov5d to
+    join multiple datasets into one output file.
+
+h5utils 1.3 (1/21/00)
+
+  * You can now specify individual datasets within a file by using
+    <filename>:<dataset> instead of just <filename> with h5topng,
+    h5totxt, and h5tov5d.
+
+h5utils 1.2.3: (1/20/00)
+
+  * Fixed minor bug in 'h5totxt -h'.
+
+h5utils 1.2.2: (1/12/00)
+
+  * Makefile now includes CPPFLAGS in the compiler flags, making it
+    easier to use header files in non-standard locations.  (CPPFLAGS
+    is the proper place to put -I flags for the configure script.)
+
+h5utils 1.2.1:  (1/1/00)
+
+  * Modified -o option of h5tov5d to join datasets into a single Vis5d file.
+
+h5utils 1.2:  (12/31/99)
+
+  * Added h5tov5d program for converting to Vis5d format.
+
+  * Improved installation; h5read.oct now goes into the sitewide Octave
+    plugins directory, and things work correctly when only some of the
+    utilities are compiled.
+
+h5utils 1.1:  (12/6/99)
+
+  * Added h5totxt program for exporting 2d slices of HDF5 files to text
+    suitable for importing into a spreadsheet.
+
+h5utils 1.0:  (11/22/99)
+
+  * Initial release.

+			       h5utils
+		  http://ab-initio.mit.edu/h5utils/
+
+h5utils is a set of utilities for visualization and conversion of
+scientific data in the free, portable HDF5 format.  HDF5 was developed
+in the National Center for Supercomputing Applications at the
+University of Illinois.
+
+Besides providing a simple tool for batch visualization as PNG images,
+h5utils also includes programs to convert HDF5 datasets into the
+formats required by other free visualization software (e.g. plain
+text, Vis5d, and VTK).
+
+The included utilities are:
+
+    * h5fromtxt and h5totxt: convert ASCII data (e.g. comma or tab
+      delimited) to/from HDF5.
+    * h5topng: convert 2d slices of HDF5 datasets to PNG images, with
+      a variety of color tables and other options.
+    * h5tov5d: convert HDF5 datasets to the format used by the free
+      3d+ visualization tool Vis5d.
+    * h5tovtk: convert HDF5 datasets to VTK format for use by the free
+      Visualization ToolKit (along with supporting programs like MayaVi).
+    * h5read.oct: a plug-in for GNU Octave (a Matlab-like program) to
+      read 2d slices of HDF5 datasets (the latest versions of Octave
+      include native support for HDF5).
+    * h5fromh4: convert HDF (version 4) datasets to HDF5; mostly
+      superceded by the h4toh5 program included with recent versins of HDF5.
+
+This package is developed by Steven G. Johnson (stevenj at alum.mit.edu),
+and is free software that should easily install under any Unix-like
+operating system (e.g. GNU/Linux).

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+.SH NAME
+h5fromh4 \- convert HDF4 scientific datasets to an HDF5 file
+.SH SYNOPSIS
+.B h5fromh4
+[\fIOPTION\fR]... [\fIHDF4FILE\fR]...
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5fromh4 takes one or more files in HDF4 format and outputs files in
+HDF5 format containing the datasets from the HDF4 files.  (Currently,
+only a single dataset per HDF4 file is converted.)
+
+HDF4 and HDF5 are free, portable binary formats and supporting libraries
+developed by the National Center for Supercomputing Applications at
+the University of Illinois in Urbana-Champaign.
+
+A single
+.I h5
+file can contain multiple data sets; by default,
+.I h5fromh4
+creates a dataset called "data", but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR with the
+.B -o
+option.  The
+.B -a
+option can be used to append new datasets to an existing HDF5 file.
+If the
+.B -o
+option is used and multiple HDF4 files are specified, all the HDF4
+datasets are output into that HDF5 file with the input filenames
+(minus the ".hdf" suffix) used as the dataset names.
+
+The most basic usage is something like \'h5fromh4 foo.hdf\', which
+will output a file foo.h5 containing the scientific dataset from
+foo.hdf.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h5fromh4.
+.TP
+.B -v
+Verbose output.
+.TP
+.B -a
+If the HDF5 output file already exists, append the data as a new
+dataset rather than overwriting the file (the default behavior).  An
+existing dataset of the same name within the file is overwritten,
+however.
+.TP
+\fB\-o\fR \fIfile\fR
+Send HDF5 output to
+.I file
+rather than to the input filename with .hdf replaced with .h5 (the
+default).  If multiple input files were specified, this causes all
+input datasets to be stored in
+.I file
+(rather than in separate files), with the input filenames (minus the .hdf

+.TH H5FROMTXT 1 "March 9, 2002" "h5utils" "h5utils"
+.SH NAME
+h5fromtxt \- convert text input to an HDF5 file
+.SH SYNOPSIS
+.B h5fromtxt
+[\fIOPTION\fR]... [\fIHDF5FILE\fR]
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5fromtxt takes a series of numbers from standard input and outputs a
+multi-dimensional numeric dataset in an HDF5 file.
+
+HDF5 is a free, portable binary format and supporting library developed
+by the National Center for Supercomputing Applications at the University
+of Illinois in Urbana-Champaign.  A single
+.I h5
+file can contain multiple data sets; by default,
+.I h5fromtxt
+creates a dataset called "data", but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.  The
+.B -a
+option can be used to append new datasets to an existing HDF5 file.
+
+All characters besides the numbers (and associated decimal points,
+etcetera) in the input are ignored.  By default, the data is assumed
+to be a two-dimensional MxN dataset where M is the number of rows
+(delimited by newlines) and N is the number of columns.  In this case,
+it is an error for the number of columns to vary between rows.  If M
+or N is 1 then the data is written as a one-dimensional dataset.
+
+Alternatively, you can specify the dimensions of the data explicitly
+via the
+.B -n
+.I size
+option, where
+.I size
+is e.g. "2x2x2".  In this case, newlines are ignored and the data is
+taken as an array of the given size stored in row-major ("C") order
+(where the last index varies most quickly as you step through the
+data).  e.g. a 2x2x2 array would be have the elements listed in the
+order: (0,0,0), (0,0,1), (0,1,0), (0,1,1), (1,0,0), (1,0,1), (1,1,0),
+(1,1,1).
+
+A simple example is:
+.IP "" 4
+h5fromtxt foo.h5 <<EOF
+.br
+1 2 3 4
+.br
+5 6 7 8
+.br
+EOF
+.PP
+which reads in a 2x4 space-delimited array from standard input.

+.TH H5MATH 1 "May 23, 2004" "h5utils" "h5utils"
+.SH NAME
+h5math \- combine/create HDF5 files with math expressions
+.SH SYNOPSIS
+.B h5math
+[\fIOPTION\fR]... \fIOUTPUT-HDF5FILE\fR [\fIINPUT-HDF5FILES\fR...]
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5math takes any number of HDF5 files as input, along with a mathematical
+expression, and combines them to produce a new HDF5 file.
+
+HDF5 is a free, portable binary format and supporting library developed
+by the National Center for Supercomputing Applications at the University
+of Illinois in Urbana-Champaign.  A single
+.I h5
+file can contain multiple data sets; by default,
+.I h5math
+creates a dataset called "h5math", but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.  The
+.B -a
+option can be used to append new datasets to an existing HDF5 file.
+The same syntax is used to specify the dataset used in the input
+file(s); by default, the first dataset (alphabetically) is used.
+
+A simple example of h5math's usage is:
+.IP "" 4
+h5math -e "d1 + 2*d2" out.h5 foo.h5 bar.h5:blah
+.PP
+which produces a new file, out.h5, by adding the first dataset in
+foo.h5 with twice the "blah" dataset in bar.h5.  In the expression
+(specified by \fB-e\fR), the first input dataset (from left to right)
+is referred to as \fId1\fR, the second as \fId2\fR, and so on.
+
+In addition to input datasets, you can also use the x/y/z coordinates
+of each point in the expression, referenced by "x" "y" and "z"
+variables (for the first three dimensions) as well as a "t" variable
+that refers to the last dimension.  By default, these are integers starting at 0 at the corner of the dataset, but the
+.B -0
+option will change the x/y/z origin to the center of the dataset (t is
+unaffected), and the
+.B -r
+.I res
+option will specify the "resolution", dividing the x/y/z coordinates
+by \fIres\fR.
+
+All of the input datasets must have the same dimensions, which are
+also the dimensions of the output.  If there are no input files, and
+you are defining the output purely by a mathematical formula, you can
+specify the dimensions of the output explicitly via the
+.B -n
+.I size
+option, where
+.I size
+is e.g. "2x2x2".
+
+Sometimes, however, you want to use only a smaller-dimensional "slice"
+of multi-dimensional data.  To do this, you specify coordinates in one
+(or more) slice dimension(s), via the
+.B -xyzt
+options.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h5math.
+.TP
+.B -v
+Verbose output.
+.TP
+.B -a
+If the HDF5 output file already exists, append the data as a new
+dataset rather than overwriting the file (the default behavior).  An
+existing dataset of the same name within the file is overwritten,
+however.
+.TP
+\fB\-e\fR \fIexpression\fR
+Specify the mathematical expression that is used to construct the
+output (generally in " quotes to group the expression as one item in
+the shell), in terms of the variables for the input datasets and
+the coordinates as described above.
+
+Expressions use a C-like infix notation, with most standard operators
+and mathematical functions (+, sin, etc.) being supported.  This
+functionality is provided (and its features determined) by GNU libmatheval.
+.TP
+\fB\-f\fR \fIfilename\fR
+Name of a text file to read the expression from, if no
+.B -e
+expression is specified.  Defaults to stdin.
+.TP
+\fB\-x\fR \fIix\fR, \fB\-y\fR \fIiy\fR, \fB\-z\fR \fIiz\fR, \fB\-t\fR \fIit\fR
+This tells
+.I h5math
+to use a particular slice of a multi-dimensional dataset.  e.g.
+.B -x
+uses the subset (with one less dimension) at an x index of
+.I ix
+(where the indices run from zero to one less than the maximum index in
+that direction).  Here, x/y/z correspond to the first/second/third
+dimensions of the HDF5 dataset. The \fB\-t\fR option specifies a slice
+in the last dimension, whichever that might be.  See also the
+.B -0
+option to shift the origin of the x/y/z slice coordinates to the
+dataset center.
+.TP
+.B -0
+Shift the origin of the x/y/z slice coordinates to the dataset center,
+so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x
+plane of the dataset instead of the edge x plane.  (\fB\-t\fR
+coordinates are not affected.)
+
+This also shifts the origin of the x/y/z variables in the expression so
+that 0 is the center of the dataset.
+.TP
+\fB\-r\fR \fIres\fR
+Use a resolution
+.I res
+for x/y/z (but not t) variables in the expression, so that the data
+"grid" coordinates are divided by \fIres\fR.  The default \fIres\fR is 1.
+
+For example, if the x dimension has 21 grid steps, setting a \fIres\fR
+of 20 will mean that x variables in the expression run from 0.0 to
+1.0 (or -0.5 to 0.5 if \fB\-0\fR is specified), instead of 0 to 20.
+
+.B -r
+does not affect the coordinates used for slices, which are always integers.
+.TP
+\fB\-n\fR \fIsize\fR
+The output dataset must be the same size as the input datasets.  If
+there are no input datasets (if you are defining the output purely by
+a formula), then you must specify the output size manually with this
+option: \fIsize\fR is of the form MxNxLx... (with M, N, L being
+integers) and may be of any dimensionality.
+.TP
+\fB\-d\fR \fIname\fR
+Write to dataset
+.I name
+in the output; otherwise, the output dataset is called "data" by default.
+Also use dataset
+.I name
+in the input; otherwise, the first input dataset (alphabetically) in a
+file is used.  Alternatively, use the syntax \fIHDF5FILE:DATASET\fR
+(which overrides the
+.B -d
+option).

+.SH NAME
+h5topng \- generate PNG images from 2d slices of HDF5 files
+.SH SYNOPSIS
+.B h5topng
+[\fIOPTION\fR]... [\fIHDF5FILE\fR]...
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5topng is a utility to generate images in PNG (Portable Network Graphics)
+format from two-dimensional slices of datasets in HDF5 files.  It is
+designed for quick-and-dirty visualization of scientific data, and for
+batch processing thereof via shell scripts.
+
+HDF5 is a free, portable binary format and supporting library developed
+by the National Center for Supercomputing Applications at the University
+of Illinois in Urbana-Champaign.  A single
+.I h5
+file can contain multiple data sets; by default,
+.I h5topng
+takes the first dataset, but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.
+
+For a three- or four-dimensional dataset you must specify coordinates
+in one or two slice dimensions, respectively, to get a two-dimensional
+slice, via the
+.B -xyzt
+options.  Yet more options control things like the colormap and
+magnification.  Still, the most basic usage is something like
+\'h5topng foo.h5\', which will output a file foo.png containing an
+image from the two-dimensional data in foo.h5.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h5topng.
+.TP
+.B -v
+Verbose output.  This output includes the minimum and maximum values
+encountered in the data, which is useful to know for the
+.B -mM
+options.
+.TP
+\fB\-o\fR \fIfile\fR
+Send PNG output to
+.I file
+rather than to the filename with .h5 replaced with .png (the default).
+.TP
+\fB\-x\fR \fIix\fR, \fB\-y\fR \fIiy\fR, \fB\-z\fR \fIiz\fR, \fB\-t\fR \fIit\fR
+This tells
+.I h5topng
+to use a particular slice of a multi-dimensional dataset.  e.g.
+.B -x
+causes a yz plane (of a 3d dataset) to be used, at an x index of
+.I ix
+(where the indices run from zero to one less than the maximum index in
+that direction).  Here, x/y/z correspond to the first/second/third
+dimensions of the HDF5 dataset. The \fB\-t\fR option specifies a slice
+in the last dimension, whichever that might be.  See also the
+.B -0
+option to shift the origin of the x/y/z slice coordinates to the
+dataset center.
+
+Instead of specifying a single index as an argument to these options,
+you can also specify a range of indices in a Matlab-like notation:
+\fIstart\fR:\fIstep\fR:\fIend\fR or \fIstart\fR:\fIend\fR
+(\fIstep\fR defaults to 1).  This loops over that slice index, from
+\fIstart\fR to \fIend\fR in steps of \fIstep\fR, producing a
+sequence of output PNG files (with the slice index appended to the
+filename, before the ".png").
+.TP
+.B -0
+Shift the origin of the x/y/z slice coordinates to the dataset center,
+so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x
+plane of the dataset instead of the edge x plane.  (\fB\-t\fR
+coordinates are not affected.)
+.TP
+\fB\-X\fR \fIscalex\fR, \fB\-Y\fR \fIscaley\fR, \fB\-S\fR \fIscale\fR
+Scale the x and y dimensions of the image by
+.I scalex
+and
+.I scaley
+respectively.  The
+.B -S
+option scales both x and y.  The default is to use scale factors of 1.0;
+i.e. the image has the same dimensions (in pixels) as the data.  Linear
+interpolation is used to fill in the pixels when the scale factors are
+not 1.0.
+.TP
+\fB\-s\fR \fIskewangle\fR
+Skew the image by
+.I skewangle
+(in degrees) to the left or right.  The result is a parallelogram, with
+the leftover space in the (square) image filled with either black or white
+pixels, depending upon the color map.
+.TP
+.B -T
+Transpose the data (interchange the image axes).  By default,
+the first (x) coordinate of the data corresponds to the columns,
+and the second (y) coordinate corresponds to the rows; transposition
+reverses this convention.
+.TP
+.B -c \fIcolormap\fR
+Use a color map 
+.I colormap
+rather than the default
+.B gray
+color map (a grayscale ramp from white to black).
+.I colormap
+is normally the name of one of the color maps provided with 
+.I h5topng
+(in the @datadir_val@/h5utils/colormaps directory), or can instead be
+the name of a color-map file.
+
+Three useful included color maps are
+.B hot
+(black-red-yellow-white, useful for intensity data),
+.B bluered
+(blue-white-red, useful for signed data), and
+.B hsv
+(a multi-color "rainbow").  If you use the
+.B bluered
+color map for signed data, you may also want to use the
+.B -Z
+option so that the center of the color scale (white) corresponds to
+zero.
+
+A color-map file is a sequence of whitespace-separated R G B A
+quadruples, where each value is in the range 0.0 to 1.0 and indicates
+the fraction of red/green/blue/alpha.  (An alpha of 0 is transparent
+and of 1 is opaque; this is only used for the \fB\-a\fR option,
+below.)  The colors in the color map are linearly interpolated as
+necessary to provide a continuous color ramp.
+.TP
+.B -r
+Reverse the ordering of the color map.  You can also accomplish this
+by putting a "-" before the colormap name in the 
+.B -c
+or
+.B -a
+option.
+.TP
+.B -Z
+Center the color scale on the value zero in the data.
+.TP
+\fB\-m\fR \fImin\fR, \fB\-M\fR \fImax\fR
+Normally, the bottom and top of the color map correspond to the
+minimum and maximum values in the data.  Using these options, you
+can make the bottom and top of the color map correspond to
+.I min
+and
+.I max
+instead.  Data values below or above this range will be treated as if
+they were
+.I min
+or
+.I max
+respectively.  See also the
+.B -Z
+and
+.B -R
+options.
+.TP
+.B -R
+When multiple files are specified, set the bottom and top of the color
+maps according to the minimum and maximum over all the data.  This is
+useful to process many files using a consistent color scale, since
+otherwise the scale is set for each file individually.
+.TP
+\fB\-C\fR \fIfile\fR, \fB\-b\fR \fIval\fR
+Superimpose contour outlines from the first dataset in the
+.I file
+HDF5 file on all of the output images.  (If the contour dataset does
+not have the same dimensions as the output data, it is peridically
+"tiled" over the output.)  You can use the syntax
+.I file:dataset
+to specify a particular dataset within the file.  The contour outlines
+are around a value of
+.I val
+(defaults to middle of value range in \fIfile\fR).
+.TP
+\fB\-A\fR \fIfile\fR, \fB\-a\fR \fIcolormap\fR:\fIopacity\fR
+Translucently overlay the data from the first dataset in the
+.I file
+HDF5 file, which should have the same dimensions as the input
+dataset, on all of the output images, using the colormap
+.I colormap
+with opacity (from 0 for completely transparent to 1 for completely opaque)
+.I opacity
+multiplied by the opacity (alpha) values in the colormap.  (If the
+overlay dataset does not have the same dimensions as the output data,
+it is peridically "tiled" over the output.)  You can use the syntax
+.I file:dataset
+to specify a particular dataset within the file.
+
+Some predefined colormaps that work particularly well for this feature
+are 
+.B yellow
+(transparent white to opaque yellow) 
+.B gray
+(transparent white to opaque black),
+.B yarg
+(transparent black to opaque white), 
+.B green
+(transparent white to opaque green), and
+.B bluered
+(opaque blue to transparent white to opaque red).  You can prepend "-"
+to the colormap name to reverse the colormap order.  (See also
+\fB\-c\fR, above.)  The default for \fB\-a\fR is yellow:0.3 (yellow
+colormap multiplied by 30% opacity).
+.TP
+\fB\-d\fR \fIname\fR
+Use dataset
+.I name
+from the input files; otherwise, the first dataset from each file is used.
+Alternatively, use the syntax \fIHDF5FILE:DATASET\fR, which allows you
+to specify a different dataset for each file.
+You can use the
+.I h5ls
+command (included with hdf5) to find the names of datasets within a file.
+.TP
+.B -8
+Use 8-bit (indexed) color for the PNG output, instead of 24-bit (direct)
+color (the default).  (This shrinks the image size slightly, with some
+degradation in quality.)  Not supported in conjunction with the \fB\-A\fR
+(translucent overlay) option.

+.SH NAME
+h5totxt \- generate comma-delimited text from 2d slices of HDF5 files
+.SH SYNOPSIS
+.B h5totxt
+[\fIOPTION\fR]... [\fIHDF5FILE\fR]...
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5totxt is a utility to generate comma-delimited text (and similar
+formats) from one-, two-, or more-dimensional slices of numeric
+datasets in HDF5 files.  This way, the data can easily be imported
+into spreadsheets and similar programs for analysis and visualization.
+
+HDF5 is a free, portable binary format and supporting library developed
+by the National Center for Supercomputing Applications at the University
+of Illinois in Urbana-Champaign.  A single
+.I h5
+file can contain multiple data sets; by default,
+.I h5totxt
+takes the first dataset, but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.
+
+By default, the entire dataset is dumped to the output.  in row-major
+order.  For 3d datasets, this corresponds to a sequence of yz slices,
+in order of increasing x, separated by blank lines.  If
+.B -T
+is specified, outputs in the transposed (column-major) order instead
+
+Often, however, you want only a one- or two-dimensional slice of
+multi-dimensional data.  To do this, you specify coordinates in one or
+more slice dimensions, via the
+.B -xyzt
+options.
+
+The most basic usage is something like \'h5totxt foo.h5\', which will
+output comma-delimited text to stdout from the data in foo.h5.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h5totxt.
+.TP
+.B -v
+Verbose output.
+.TP
+\fB\-o\fR \fIfile\fR
+Send text output to
+.I file
+rather than to stdout (the default).
+.TP
+\fB\-s\fR \fIsep\fR
+Use the string
+.I sep
+to separate columns of the output rather than a comma (the default).
+.TP
+\fB\-x\fR \fIix\fR, \fB\-y\fR \fIiy\fR, \fB\-z\fR \fIiz\fR, \fB\-t\fR \fIit\fR
+This tells
+.I h5totxt
+to use a particular slice of a multi-dimensional dataset.  e.g.
+.B -x
+causes a yz plane (of a 3d dataset) to be used, at an x index of
+.I ix
+(where the indices run from zero to one less than the maximum index in
+that direction).  Here, x/y/z correspond to the first/second/third
+dimensions of the HDF5 dataset. The \fB\-t\fR option specifies a slice
+in the last dimension, whichever that might be.  See also the
+.B -0
+option to shift the origin of the x/y/z slice coordinates to the
+dataset center.
+.TP
+.B -0
+Shift the origin of the x/y/z slice coordinates to the dataset center,
+so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x
+plane of the dataset instead of the edge x plane.  (\fB\-t\fR
+coordinates are not affected.)
+.TP
+.B -T
+Transpose the data (interchange the dimension ordering).  By default, no
+transposition is done.
+.TP
+\fB\-.\fR \fInumdigits\fR
+Output
+.I numdigits
+digits after the decimal point (defaults to 16).
+.TP
+\fB\-d\fR \fIname\fR
+Use dataset
+.I name
+from the input files; otherwise, the first dataset from each file is used.
+Alternatively, use the syntax \fIHDF5FILE:DATASET\fR, which allows you
+to specify a different dataset for each file.
+You can use the
+.I h5ls
+command (included with hdf5) to find the names of datasets within a file.

+.SH NAME
+h5tov5d \- convert datasets in HDF5 files to Vis5d format
+.SH SYNOPSIS
+.B h5tov5d
+[\fIOPTION\fR]... [\fIHDF5FILE\fR]...
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5tov5d is a program to generate Vis5d data files from
+multidimensional datasets in HDF5 files.  Vis5d is a free volumetric
+visualization program capable of displaying 3, 4, or even 5
+dimensional datasets (using time for the 4th dimension and different
+variables for the 5th dimension).
+
+HDF5 is a free, portable binary format and supporting library developed
+by the National Center for Supercomputing Applications at the University
+of Illinois in Urbana-Champaign.  A single
+.I h5
+file can contain multiple data sets; by default,
+.I h5tov5d
+takes the first dataset, but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.
+
+1d/2d/3d datasets are converted into 3d Vis5d datasets. 4d datasets
+are converted into a time series of 3d datasets, with the first
+dimension marking the time.  5d datasets are converted into several
+variables of time series of 3d datasets, with the first dimension as
+the variable index and the second dimension as the time.  Often,
+however, you want only a three-dimensional "slice" of four (or more)
+dimensional data.  To do this, you specify coordinates in one (or
+more) slice dimension(s), via the
+.B -xyzt
+options.
+
+A typical invocation is of the form
+\'h5tov5d foo.h5\', which will output a Vis5d data file foo.v5d
+from the data in foo.h5.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h5tov5d.
+.TP
+.B -v
+Verbose output.
+.TP
+.B -T
+Transpose the output dimensions (reverse their order).
+.TP
+\fB\-o\fR \fIfile\fR
+Save the datasets from all of the input files to a single Vis5d
+.I file
+with each dataset being expressed as a separate Vis5d variable.  In
+this way, you can use Vis5d to superimpose and compare the plots from
+the different datasets.  The first two dimensions (or three, for 4d
+datasets) must be the same for all of the input datasets.
+
+Otherwise, the default behavior is to save each dataset to a separate
+Vis5d file, with the .h5 suffix of the input filename replaced by .v5d
+in the output filename.
+.TP
+\fB\-1\fR, \fB\-2\fR, \fB\-4\fR
+Use 1 (the default), 2, or 4 bytes to store each data point in the
+output file.  Fewer bytes will cause Vis5d to be faster (as well as
+requiring less storage and memory), but will decrease the resolution
+in the values.
+.B -1
+will break up the data values into one of 256 possible values (on a
+linear scale from the minimum to the maximum value in your data),
+.B -2
+will allow 65536 possible values, and
+.B -4
+will use 4-byte floating-point numbers for an "exact" representation.
+In most circumstances,
+.B -1
+is more than adequate for data visualization purposes.
+.TP
+\fB\-x\fR \fIix\fR, \fB\-y\fR \fIiy\fR, \fB\-z\fR \fIiz\fR, \fB\-t\fR \fIit\fR
+This tells
+.I h5tov5d
+to use a particular slice of a multi-dimensional dataset.  e.g.
+.B -x
+uses the subset (with one less dimension) at an x index of
+.I ix
+(where the indices run from zero to one less than the maximum index in
+that direction).  Here, x/y/z correspond to the first/second/third
+dimensions of the HDF5 dataset. The \fB\-t\fR option specifies a slice
+in the last dimension, whichever that might be.  See also the
+.B -0
+option to shift the origin of the x/y/z slice coordinates to the
+dataset center.
+.TP
+.B -0
+Shift the origin of the x/y/z slice coordinates to the dataset center,
+so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x
+plane of the dataset instead of the edge x plane.  (\fB\-t\fR
+coordinates are not affected.)
+.TP
+\fB\-d\fR \fIname\fR
+Use dataset
+.I name
+from the input files; otherwise, the first dataset from each file is used.
+Alternatively, use the syntax \fIHDF5FILE:DATASET\fR, which allows you
+to specify a different dataset for each file.
+You can use the
+.I h5ls
+command (included with hdf5) to find the names of datasets within a file.

+.SH NAME
+h5tovtk \- convert datasets in HDF5 files to VTK format
+.SH SYNOPSIS
+.B h5tovtk
+[\fIOPTION\fR]... [\fIHDF5FILE\fR]...
+.SH DESCRIPTION
+.PP
+." Add any additional description here
+h5tovtk is a program to generate VTK data files from multidimensional
+datasets in HDF5 files.  VTK, the Visualization ToolKit, is an
+open-source, freely available software system for 3D computer
+graphics, image processing, and visualization.  VTK itself is a
+programming library, but it is also the basis for a number of end-user
+graphical visualization programs.
+
+HDF5 is a free, portable binary format and supporting library developed
+by the National Center for Supercomputing Applications at the University
+of Illinois in Urbana-Champaign.  A single
+.I h5
+file can contain multiple datasets; by default,
+.I h5tovtk
+takes the first dataset, but this can be changed via the
+.B -d
+option, or by using the syntax \fIHDF5FILE:DATASET\fR.
+
+1d/2d/3d datasets are converted into 3d VTK \"structured points\"
+datasets.  Normally, a single scalar VTK dataset is output, but
+vectors and fields can be output via the
+.B -o
+option below.
+
+A typical invocation is of the form
+\'h5tovtk foo.h5\', which will output a VTK data file foo.vtk
+from the data in foo.h5.
+.SH OPTIONS
+.TP
+.B -h
+Display help on the command-line options and usage.
+.TP
+.B -V
+Print the version number and copyright info for h5tovtk.
+.TP
+.B -v
+Verbose output.
+.TP
+\fB\-o\fR \fIfile\fR
+Save all the input datasets to a single VTK \fIfile\fR.  If there is
+only one dataset, it is output to a VTK scalar dataset; if there are
+three datasets, they are output as a VTK vector dataset; all other
+numbers of datasets are combined into a VTK field dataset.
+
+Otherwise, the default behavior is to save each dataset to a separate
+VTK file, with the .h5 suffix of the input filename replaced by .vtk
+in the output filename.
+
+Only three-dimensional datasets may be written to the VTK file.  If
+you have a four (or more) dimensional data set, then you must take a
+three-dimensional "slice" of the multi-dimensional data.  To do this,
+you specify coordinates in one (or more) slice dimension(s), via the
+.B -xyzt
+options.
+.SH OPTIONS
+.TP
+\fB\-1\fR, \fB\-2\fR, \fB\-4\fR
+Use 1 , 2, or 4 bytes to store each data point in the
+output file.  Fewer bytes require less storage and memory,
+but will decrease the resolution in the values.
+.B -1
+will break up the data values into one of 256 possible values (on a
+linear scale from the minimum to the maximum value in your data),
+.B -2
+will allow 65536 possible values, and
+.B -4
+(the default) will use 4-byte floating-point numbers for an "exact"
+representation.
+.TP
+.B -a
+Output in ASCII format; otherwise, VTK's more compact, but less
+readable and somewhat less portable binary format is used.
+.TP
+.B -n
+For binary output (see
+.B -a
+above), by default the data is written in bigendian byte order, which
+is normally the order that VTK expects.  However, some external tools
+and a few VTK classes use the native byte ordering instead (which may
+not be bigendian), and the
+.B -n
+option causes
+.I h5tovtk
+to output binary data in the native ordering.
+.TP
+\fB\-m\fR \fImin\fR, \fB\-M\fR \fImax\fR
+When
+.B -1
+or
+.B -2
+are used, the input data are converted to a linear integer scale.
+Normally, the bottom and top of this scale correspond to the
+minimum and maximum values in the data.  Using the
+.B -m
+and
+.B -M
+options, you
+can make the bottom and top of the scale correspond to
+.I min
+and
+.I max
+instead, respectively.  Data values below or above this range will be
+treated as if they were
+.I min
+or
+.I max
+respectively.  See also the
+.B -Z
+option.
+.TP
+.B -Z
+For
+.B -1
+or
+.B -2
+output, center the linear integer scale on the value zero in the data.
+.TP
+.B -r

+.TP
+\fB\-x\fR \fIix\fR, \fB\-y\fR \fIiy\fR, \fB\-z\fR \fIiz\fR, \fB\-t\fR \fIit\fR
+This tells
+.I h5tovtk
+to use a particular slice of a multi-dimensional dataset.  e.g.
+.B -x
+uses the subset (with one less dimension) at an x index of
+.I ix
+(where the indices run from zero to one less than the maximum index in
+that direction).  Here, x/y/z correspond to the first/second/third
+dimensions of the HDF5 dataset. The \fB\-t\fR option specifies a slice
+in the last dimension, whichever that might be.  See also the
+.B -0
+option to shift the origin of the x/y/z slice coordinates to the
+dataset center.
+.TP
+.B -0
+Shift the origin of the x/y/z slice coordinates to the dataset center,
+so that e.g. -0 -x 0 (or more compactly -0x0) returns the central x
+plane of the dataset instead of the edge x plane.  (\fB\-t\fR
+coordinates are not affected.)
+.TP
+\fB\-d\fR \fIname\fR
+Use dataset
+.I name
+from the input files; otherwise, the first dataset from each file is used.
+Alternatively, use the syntax \fIHDF5FILE:DATASET\fR, which allows you
+to specify a different dataset for each file.
+You can use the
+.I h5ls
+command (included with hdf5) to find the names of datasets within a file.
