Hi Jean-Claude, 
I't be nice if you could get your MUA (probably Outlook Express) to break 
long lines ;-)   See here: http://www.md.kth.se/~chr/etc/outlook/

This page is a good stop:
	http://www.php.net/manual/en/ref.pcre.php

and just like there is a special "mode" in emacs for interactively working 
with regexp:s, the page above gives a link to something similar for 
Perl-compatible regexps:
	http://www.weitz.de/regex-coach/
(Note: the regexp you enter here is not 'quoted', so before using it in 
your php-code, you'll have to quote '\' as '\\')

IIRC, the above page also has links to other tools/tips for working with 
regexps.
