Jason Orendorff has a wonderfully Pythonic replacement for os.path at 

    http://www.jorendorff.com/articles/python/path/

A short example from the page above:

    from path import path  # Jason's path, not os.path
    dir = path(os.environ['HOME'])
    for f in dir.walkfiles('*~'):
        f.remove()

Each of the path.walk... methods (one for files, one for directories,
one for both) returns a generator that yields the elements in the path
tree. The globbing pattern is optional.

I'd love to see 'path' become a standard module. Maybe it could be a
subpackage of os.path... though "from os.path.path import path" does
seem a *bit* verbose. ;-)
