As far as I know, it's equivalent to three steps:

1) Download the appropriate version of a package (the latest, if you
didn't say otherwise)
2) Extract that package
3) Run 'python setup.py'.

What setup.py does is up to the package, but for a pure-Python package
it should simply create something in site-packages. It might do a lot
more, though - compiling C or Fortran code, for instance.
