* Useful for packaging on platforms where we can only build from tarballs (FreeBSD)
* I don't know whether it's always safe and correct to install this file into $DATADIR/applications,
  so the file is only distributed but not installed yet.
* It contains a hardcoded binary name "gsciteco". This could actually differ
  depending on the concrete --program-prefix and it would be good to include the exact
  installation path.
  This however is not possible as long as we do not install this file.

* Added a Freedesktop file - only as part of the debian package yet.
  `make install` won't install a Desktop file since it would have to be
  generated.
* Just like when installing manually, you can have a Curses and Gtk installation
  side by side using the same .teco_ini.
* Common data between the Curses UI (sciteco-curses) and Gtk UI are in a new
  architecture-independant package sciteco-common.
* The Gtk+ binaries are prefixed with `g` (gsciteco, gtedoc.tes, ggrosciteco.tes).
* Debian source and binary packages can be built using `./distribute.mk debian`
  as usual.
  It should also be possible to push everything to the PPA for the next release,
  although that is not yet tested.
