That one missed necessary changes to debian/control.in and hence still
produced a (more or less empty) libplplot-d package, so I've
redesigned the whole patch to use the already present
debian/control.in which now has a few more slices which can be left out.

I also reworked the disabling of Octave support from the previous NMU
to use this system. Previously only the ADA support used that feature.

So now:

* debian/control.in contains _all_ packages, all build-dependencies
  and all bindings mentioned in libplplot-dev's long package
  description.

* Depending on the BUILD_* variables at the beginning of debian/rules,
  debian/control gets rewritten by including or excluding the marked
  slices in debian/control.in.

  For build-architecture-dependent inclusion/exclusion this is always
  done at build-time, but with "debian/rules control" this can be done
  by the maintainer before building a source package to upload to also
  adjust the build-dependencies.

* If you change the BUILD_* variables at the beginning of
  debian/rules, run "debian/rules control" once locally to update the
  build-dependencies accordingly.

IMHO this is much cleaner than commenting out and in binary package
stanzas in debian/control, also because all the infrastructure for
doing so is already in the package. Just had to use it.

Since because of the above, the debdiff is slightly complexer than and
especially very different to my previous patch. I've also documented
the above in debian/README.source. (And noticed that way that it was a
hint how to use quilt despite the package was already source format
"3.0 (quilt)" and hence the file's previous content was already
obsolete.)

So I've attached a full debdiff again and uploaded the package only to
DELAYED/5.

If anyone thinks that I should fast-forward it nevertheless, feel free
to tell me.

		Regards, Axel

 ========================
 
-This package uses quilt to manage all modifications to the upstream sources.
-See `/usr/share/doc/quilt/README.source' to get more information on how to
-use it.
+This package uses debian/rules, debian/control.in and the tool slice
+to generate a debian/control file which contains only those binary
+package stanzas, package descriptions parts and build-dependencies for
+those language bindings which should be build.
 
- -- Rafael Laboissiere <rafael at debian.org>  Thu, 23 Apr 2009 09:13:07 +0100
+See the beginning of debian/rules for the according BUILD_*
+variables. Run "debian/rules control" after you've changed them to
+rebuild debian/control accordingly.
+
+debian/control is rebuild at build-time anyways to accomodate
+architecture-dependent changes like automatic disabling of ADA support
+on sh4, etc. But while this also changes the source stanza, it doesn't
+really affect the build-dependencies as they are parsed in advance.
