World: r3wp

Any one knows how do I find rebolek's R2E2 - REBOL Regular Expressions 
Engine. 
This link is dead I think http://bolek.techno.cz/reb/regex.r

I saw it on http://www.rebol.org/documentation.r?script=regset.r

Endo, I will try to find newest version and let you know. But do 
not expect it to translate every regular expession.

Thank you, I don't need an exact regexp library, but would be nice 
to have some regexp functionality.
