module file

[Imbaud Pierre]

I am willing to retrieve the file an imported module came from;
module.__file__, or inspect.getfile(module) only gives me the
relative file name. How do I determine the path?
Its obviously possible from python: ipython displays the information
(interactively: *module?*).
