Welcome!
Probably the best way to contribute to the code would be to use it for
your own work and add any capabilities you need. I'd love to see more
perturbation theory / structure formation stuff included. Please post
to the group about things you intend to add so we don't duplicate too
much effort. And of course, please post any question that arise as you
use and modify the code.
I encourage anyone interested in contributing to use git (
http://git-
scm.com/). Getting started is as simple as running (once you have git
installed):
> git clone git://
github.com/roban/CosmoloPy
Then once you've edited some files,
> git add (files)
> git commit -m 'Explain what I changed'
> git format-patch origin/master
