cron things

Hi,

OK, we currently have

<root-cron-fragment>
..blah..
</root-cron-fragment>

to handle the root crontab. How should it be done for other users
crontabs? For instance, I would like a cron job in the TWiki package,
which will do the automatic email notification thing.

Should it be:

<twiki-cron-fragment>
..blah..
</twiki-cron-fragment>

or maybe:

<cron-fragment>
<code privileges="twiki">
..blah..
</code>
</cron-fragment>

or even a hack like:

<root-cron-fragment>
1 1 * * * /usr/local/bin/sudo -u twiki ..blah..
</root-cron-fragment>

Ideas?

Matt
