SUMMARY="compatibility layer capable of running Windows applications"
DESCRIPTION="
Wine is an implementation of the Windows API on top of X and Unix. It does not
require Microsoft Windows, but can use native Windows DLLs if they are available.
It provides both a development toolkit for porting Windows source code to Unix
as well as a program loader, allowing many unmodified Windows programs to run on
x86-based Unixes.
