Hi,
I just created http://cocan.org/comparisons (thanks to Christophe 
Raffalli for allowing me to reuse 
http://www.lama.univ-savoie.fr/~raffalli/ocaml-parsing.html)

It seems to me that a wiki is more suitable than a mailing list for this 
kind of information sharing.

Feel free to
 - add you wishes on the list of needs to compare
 - contribute to the pages (even small additions and corrections)
 - argue that wikipedia would be better for this (and do the migration)
