Indeed, distutils is great. I have written pure python modules and C
extension modules, and mixed modules, and it all works like a charm.
Plus, you have the full power of python in your setup.py script so you
can do lots of neat things.

What do you mean distutils not selecting compilers? It finds gcc on my
linux machine and on Solaris, and I think it probes for some windows
compilers too. I don't know about e.g. macos.

Not all compilers *have* an interactive mode, do they? I thought nhc98
was just a compiler? This makes it tricky.

Another problem is that when you run  'hugs File.hs' or 'ghci File.hs',
they start interactive mode, 'python file.py' runs the program. Are
there flags to all interpreters that run main automatically? I know
there's runhugs for example, but what about ghc(i)? What about nhc98?
