Re: Suggestion about best practice with .gpr files

[Maxim Reznik <reznikmm@gmail.com>]

We use a dedicated folder `gnat/` to keep project files there. This has several a advantages:

* you doesn't pollute the root directory with extra files (as you see you need at least two project file - for library and for tests)
* a user is able to observe all project files in one place and pick up needed one
* if you tend to use the repo as mono-repo (or if you split the library into two), you will get much more project files (see Matreshka or VSS). So keep them in order is important
* people who don't use project files don't see them :D

The layout becomes

foolib/
...|
...+-- Makefile
...+--alire.toml
...+-- docs
...+-- gnat
...|
......+-- foo.gpr
......+-- foo_tests.gpr
...+-- source
...+-- testsuite

To simplify a new repository creation I made a template repo and keep common files there. Take a look, perhaps you find something useful there.
