Puredarwin is an OS based on Apple's open source Darwin releases and
doesn't include any of Apple's proprietary bits. Whereas 'macosx' is
what most of us use, OS X. Darwin in this context is the union of
puredarwin and macosx (i.e. in 'platforms' it means the port will work
on both of them, and in 'platform' statements the body will be executed
on both of them).

Cf. the os.platform and os.subplatform variables.
