[CPS-devel] Zope/CPS script scheduling

[Santi Camps]

Hi,

Another way is create .py scripts and put them in the cron.   If you need
the Zope environment, you can run this scripts using "zope/bin/zopectl run
yourscript.py"   I think ZEO is needed to perform this, but it's easy to
configure it.

Regards
