That sounds fine.  My .diffs are all in the debian directory so the
patches are cleanly separated and labeled.

It would be great to have some team maintenance for these packages.

The OpenCASCADE package is 99% complete and builds fine on unstable.  It
is missing two .dat files required for Salomé, and I have been waiting
for some free time to add in Jason's scripts to split up the binary
packages in a more sane way (maybe tomorrow?).  It's also *almost*
lintian-clean!  So I think that is nearly ready to upload, the only
question is: main or non-free...  For a discussion of this, see:

Salomé is also 99% complete (my -4 is building now, and should be ready
to post in a few hours), but is very lintian-unclean, and has dependency
      * It needs two extra netgen symbols, and needs to load the netgen
        libraries at runtime, so those need to be shared; I sent patches
        via bugs 461929 and 462105 to do these.  Haven't heard back from
        the maintainer.
      * I like OpenMPI, so I patched HDF5 to use it, and sent the patch
        via bug 457080, which the maintainers accepted.  But the
        resulting package is taking a while because of an interface
      * Salomé needs omniORB 4.0.x which is no longer in unstable (but
        is in testing); porting it to 4.1.x looks like it will take a
        very long time.  I tried to contact upstream via their web form,
        but haven't heard back.
So although Salomé is LGPL, it will be a while before can include it in
Debian.  Also, because it links with OCC (OCC license), and Qt (GPL),
the OCC license will need to be deemed GPL-compatible in order for
Salomé to be distributable. :-(
