[Distutils] Swig build_py ran before build_ext

[Jari Pennanen]

Well, if that is so, I will paste my workaround for the sake of
completeness if other people come here to wonder:

   #!/usr/bin/env python
   from distutils.core import setup, Extension
   from distutils.command.build_py import build_py

   dist = setup(...)

   # Rerun the build_py to ensure that swig generated py files are also copied
   build_py = build_py(dist)
   build_py.ensure_finalized()
   build_py.run()

Btw, this could be mentioned in
http://docs.python.org/distutils/setupscript.html since SWIG is rather
common tool... it took me a notable time to figure this out.

(Sorry about duplicate mail)
