compatibility layer capable of running Windows applications.  Instead of
simulating internal Windows logic like a virtual machine or emulator, Wine
translates Windows API calls into POSIX calls on-the-fly, eliminating the
performance and memory penalties of other methods and allowing you to cleanly
integrate Windows applications into your desktop.")
