Wine is an open-source and widely-used software project whoes main design goal is to implement a compatibility layer for running software applications that are built only for the Microsoft Windows operating system on GNU/Linux distributions, as well as Apple’s Mac OS X platform. Wine 1.9.15 is currently the latest and most advanced version of the free implementation of Windows on Unix, and it looks like the CodeWeavers developers were quick to adopt it for their commercial CrossOver application that provides an easy-to-use and intuitive GUI to Wine for Linux and Mac systems.
