Hmm, because there is no cron job on berlios server :)
If a developer with ssh access can put up a cron job on its own
server
to launch this generation script, it would be OK.
Every developer has a crontab on shell.berlios.de.
You're right. It's just the script is meant to work on svn.berlios.de.
In the end, i put up the cron on shell and have it ssh to svn (every
day, cleaned after 30 days) :p
Thanks for the hint.
