Wine makes it possible to run Windows programs alongside any
Unix-like operating system, particularly Linux. At its heart, Wine is
an implementation of the Windows Application Programing Interface (API)
library, acting as a bridge between the Windows program and Linux.
Think of Wine as a compatibility layer, when a Windows program tries to
perform a function that Linux doesn’t normally understand, Wine will
translate that program’s instruction into one supported by the system.
For example, if a program asks the system to create a Windows
pushbutton or text-edit field, Wine will convert that instruction into
its Linux equivalent in the form of a command to the window manager
using the standard X11 protocol.
