This is the old doc format which I think was used 
non-systematically, mostly because it worked OK with epydoc. 
Scipy contains still many docstrings written like this, Numpy 
contains essentially none.

This is the new format, which supersedes the old one.

The second one, I believe.

Definitely a worthwhile idea. Basically, you need to do:

	easy_install numpydoc

and then add in conf.py

	extensions = ['numpydoc']
