I'm going to take a crack at documenting the methods in the main shell class, lib/shell.rb. I even found a blog post complaining about how it's totally undocumented!

Glad you are taking this one Carol. I almost chose this one too, on the basis of that blog post!

I did a bit and submitted to redmine-- see which ones i did in issue #17.

I might get back to it later but in the meantime, anyone, feel free to work on this class, there's still plenty to do!
