Take the name "wine" with a grain of salt. It's a word play and a
traditional Unix joke where the dev thinks up a clever pun as the name
for the app.
Eg: We had more, and a better more is of course less. A better less is
naturally most. And what else would you call an improved cat other than
The wikipedia quote you gave defines what an emulator *does*, not what
it *is*, so it's not really a definition of an emulator. If it were, a
definition of my car would be "that thing that gets me to work" which
An emulator is software or hardware that pretends to be a platform that
it is not. Wine doesn't do that, it is an implementation of a spec. The
fact that it is implemented on a different platform to what the spec
designer had in mind is irrelevant. To further illustrate the point, I
have compat-libs installed on this machine so that a third party binary
(a database) can run. It was designed for a glibc 2.3 platform and this
machine is glibc 2.5. These compat-libs fit your wikiedia definition
exactly, but you would never ever call them emulators, right?
