Well, for a task that runs a couple of seconds once a day or once a
week... My first thought was "if something goes wrong, the chain is
broken and no new jobs will be scheduled anymore". From the
documentation, it seems zc.async is pretty robust so this is probably
not something I have to worry about.
I'd put a short paragraph in the readme that this is how you can do
cron jobs. Helps with the google for "zope cron", too :-)

Thanks for the info. I'll see if I can get a basic cron-with-pack
setup in one instance running.
