BD-shell is a project I started about a month ago, which aims to implement a tiny, simple, clean unix shell written in C. The Operating Systems Course at my University requires this project as part of the assesment.
I decided to publish the source code and to release it under the GPL, for two reasons:

1. Free software is better! Others can learn something from what I learned
2. Free software is better! I can learn something from what others learned

As always, I accept every kind of suggestions!
