[Zope] Scheduled tasks in Zope?

Hi, How does one set up scheduled tasks in Zope (like automatically backing up files, automatically uploading newer versions of HTML files onto ZODB once a day, etc.)? I searched a little bit and found someone (Martijn Pieters) mentioning about ZScheduler... How is that coming along? Is it OK just to launch another Python thread from an external method to take care of scheduled tasks? Or is a performance hit? How can I automatically launch the scheduler thread whenever the ZServer is up? regards, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
