USAGE

Reverse dependencies using gnatmake/gnatlink must upgrade at least to
4.6.4-1 to circumvent #680292.

BUILD

Version numbering: X.Y, where X only increases when source changes are
needed in reverse dependencies.

The lintian hardening-no-fortify-functions warning seems to be
ignorable in 5.1. "hardening-check --verbose /usr/bin/dh_ada_library"
only reports memmove and memcpy, which are not called (directly) by
any Ada code.

TODO

Accept lists for variables like LDLIBS=...

Include checks that lintian cannot do as it cannot detect Ada
packages. For example, detect if a package Build-Depends on gnat and
gnat-X.Y. This would make the call to gnatgcc --version unneeded in
the Makefile snippet.

See if library_symbol_policy in the project can be used to generate a
list of symbol versions in the Debian way.

Upload Debian tags for libraries with debtags --upload? Some tags can
be automatically deduced.
