is an implementation of the Win32 and related API's. In short, it duplicates the functionality and interfaces Windows provides to an application (or game). Or even shorter: It allows you to run Windows apps.
There are a couple of forks of the Wine code, most notably Transgaming
's Cedega, which is focused on making Windows games playable on Linux.
