# TODO:
# * Add gio-module-fam
#     Problem: cyclic dependency on gamin
#     Possible solution: build as a standalone module, set env. vars
# * Make it build without python
#     Problem: an example (test?) program needs it.
#     Possible solution: disable compilation of this example somehow
#     Reminder: add 'sed -e 's@python2\.[0-9]@python@' -i
#       $out/bin/gtester-report' to postInstall if this is solved
/*
  * Use --enable-installed-tests for GNOME-related packages,

      (they should test an already installed package)
      https://wiki.gnome.org/GnomeGoals/InstalledTests
  * Support org.freedesktop.Application, including D-Bus activation from desktop files
