You can at least rely on the Debian policy for Ada. It is nice if you
make Debian maintainers' lives easier, provided there is a Debian
maintainer for your package :)

What is adaproject?

As you have probably guessed, I detest the autotools with a vengeance.
They are slow, brittle, cryptic, unmaintainable, subtly incompatible
with other versions of themselves, and they exist only to overcome the
deficiencies and lack of portability of C and C++. We use Ada. We
don't need no stupid autotools. In simple cases, one GNAT project file
is sufficient. Nowadays, with gprmake, they can even handle multi-
language projects, so even these are "simple cases". In complex cases,
a complementary Makefile can call gnatprep or pass variables to the
project file e.g. to adjust the contents of the Source_Dirs or package
Naming. It can also simply pass build options on the gnatmake or
gprmake command line if you need to override or complement the options
in package Compiler, Linker or Binder. And this is true on all
platforms, except perhaps the most exotic ones like the ones from
Redmond, which don't even have "make" by default.

Mac OS X is much more standard than e.g. Microsoft Windows, and there
are people who care about it. They are on http://www.macada.org
