Comment:
 The GTKAda user guide is licensed separately under the GNU
 Free Documentation License with Invariant Sections and Cover Texts,
 so Debian cannot distribute it. The reference manual is also excluded
 because its generation process relies on parts of the user manual.
 .
 We take the opportunity to remove copied or generated sources and
 simplify the Debian copyright and rules files.
 .
 The src/generated/* and src/misc_generated.c sources
 are generated at build time.
 .
 The OpenGL C sources are copied from other source packages.
 .
 Ideally, the GIR files should be taken from lib*-dev packages,
 namely gtk pango glib girepository,
 but upstreams uses old and patched versions.
