I've been browsing the Pragmatic Programmer book and was taken by the
"learn something new" statement.

Since parsers have always been interesting to me, I decided on racc.

I put together a sample that I found on cmills.freesheel.org
presentation and have put a copy of it here:

Can any tell me why this  doesn't work?

I'm using ruby 1.8.4 and racc version 1.4.5.  Thanks for any guidance
you might provide.
