Just thought I'd let you know of a new site I've launched to provide documentation for contributed modules, the Contributions API.

Of course, Ubercart is in there. You can get quick access to the .module files using the block in the sidebar or using the All modules page. Hopefully it will be a useful resource for developers.

You can submit requests for more modules to be added to the site. I'm also happy to take suggestions on how to improve the site.
