A book introducing game programming using Allegro 5 has recently been written by Frédéric Drouillon, titled Allegro 5 - Programmation de jeux en C ou C++. This book is available in French, and will surely be a great read for the French-speaking Allegro 5 users. For others, the code samples available for download on the publisher’s website should be of interest as well. Check out the [books section][books] for more information.
