-- Raylib is great game programming library written by 'raysan5', you
-- can check out original C source code here 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 example, and everything works. Aim are new Ada projects.
