Into what directory should hg.c go?


FWIW, I've started hacking a bit on trying to get it compiled to an exe with

  $ python setup.py build


Not really knowing what I'm doing, but I tried overriding build_ext of disutils:

This seems to manage to compile the hg.c file so far, if I copy it into
the root dir.

Seen on terminal:

  $ python setup.py build
  ...
  running build_hgexe
  C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -IC:\Python\include -IC:\Python\PC /Tchg.c /Fobuild\temp.win-amd64-2.7\Release\hg.obj
  hg.c


which looks like a good start.
