Description

What is this "Allegro WIP" that I see people talking about?
WIP stands for "work in progress", and refers to any changes that are more recent than the last official release. WIP versions of the library can be obtained as patches from the Allegro website (http://alleg.sourceforge.net/), and are usually quite stable, although obviously not so well tested as a final release version.
