hello
I just saw a new book at
http://www.amazon.fr/exec/obidos/ASIN/2212110286/ref=br_li_lf/171-8184502-1213010

ISBN : 2212110286
published december 2001

it covers all importang scripting languages for linux including Ruby.
unfortunately may french is currently very, very limited (just started)
but maybe this is of interest to some of you who know some more french.

if someone already has read the book, maybe he/she can give a short
review becaue I migth want to read it when my french is better

regards

markus
