Yep, and Stratego.  Here is the program / papers:

heh, that jazillian is cool.  You should add to the showcase:

yeah, 100M download is definitely an inverted view from the 
programmers'.

you should definitely link to this perhaps directly in the articles 
section of the website too. :)

Ack...none of us could understand each others' tools ;)  Most of them 
are hypercomplicated beasts.  I hesitate to say what is useful and what 
is not.

I'm going to start a rewriting "blog" this morning to capture some 
thoughts about what I'd like in terms of a practical rewrite system 
that would be like sed/awk except it paid attention to syntax not just 
reg exprs. :)  I'll post something and let people know.
