-- Raylib is great game programming library written by 'raysan5' and
-- many contributors, you can check out original C source code in the
-- link below, it's under zlib license. I wrote this because of the
-- lack of good Ada bindings.
--
-- There are minor name changes, and this binding was adapted to Ada
-- programming language. That means that you can't replace few keywords
-- in your C program, and expect that everything works. Aim are new Ada
-- projects. Variadic functions and function pointers were removed.
