Hello Yann,

I've got a new version for the kdesktop_lock.py script. I changed it
that way, that the scripts remembers the status message prior to
switching status to away. Please integrate it into the wiki on [1]. Will
attachments to a wiki page be overwritten automatically? The tutorial
for it might come on the weekend.

Greetings, Nico.

This script is a wrapper for kdedesktop_lock to enable auto-status for gajim.
It switches the status to away on session locking and restores the previous status
for each account.
