Wine AppreciationWine Appreciation

Wine Is Not an Emulator

...so, what is it?

What is Wine?What is Wine?

Wine runs Windows applications on Linux

(FreeBSD and Solaris)

It does not emulate the Intel x86 processor

Wine is a translation layer

Full “reimplementation” of the Windows API

But, Windows API's are huge,

- not well documented,

- full of tricky behaviours,

- side effects, and

- no available source code!
