I gave a presentation to the Northern Virginia Linux Users Group. The 
presentation is actually online. It is using eRuby and there is an entire
demonstration program available that deals with CVS user management in
regards to CVSROOT/writers and CVSROOT/readers as well as CVSROOT/passwd.

It doesnt have any checks and is only meant as an example, but it works and
actually demonstrates classes, some std lib stuff, and some other functionality.
Feel free to use it or take a gander at it whatever. If you have net access
during your presentation, it is all run thru eRuby.

Heres the link:

click on the little < > at the top to move through...When I wrote this 
presentation it was basically shortly after having devoured the Programming
Ruby book, I was(am) still quite new to Ruby myself. Glad to hear yet another
person is advocating its use! It is a great language and does OO so well that
as a person who favors procedural, Im really enjoying it.

Do what you think is interesting, do something 
that you think is fun and worthwhile, because 
otherwise you won't do it well anyway.
