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.
CrossOver Office allows you to install your favorite Windows productivity applications in Linux, without needing a Microsoft Operating System license. It includes an easy-to-use, single-click interface, which makes installing a Windows application simple and fast. Once installed, your application will integrate directly with your GNOME or KDE environment.
