[Distutils-sig] Compilers module

[John Skaller]

Well, for those who haven't looked at interscript, here is the
compilers module for comment. These modules work with gcc on my
box. The idea is to _require_ the client implement these
modules (providing some common implementation such as this one).

That way, there is a standard _interface_ for compiling
external tools and python modules, which can be used
by author build software in a platform independent way.
