[GnomeMeeting-devel-list] Do you like smileys?

[PUYDT Julien <julien puydt laposte net>]

Hi,

the attached program uses a regex, and tests it against all smileys
recognized by gnomemeeting.

This is an awful regex. I would need help to make it better; I see
several ways it could happen:
* decide to remove some smileys, that are unused, and make the regex
longer;
* add smileys, that really should be there, and whose absence makes the
regex longer;
* be smarter than myself, and come up with a wonderfully efficient&good
regex.
