Cronjob Wrapper for Docweb

This directory tree allows pseudo-crontab manipulation whenever CVS updates,
avoiding the need for manual editing of the doc.php.net crontab.

For each script that should run at a regular interval (currently hourly,
daily, weekly, monthly), place a wrapper for this script in the appropriate
sub-directory.

The actual crontab for docweb should look something like this:
0 * * * * /path/to/docweb/cron/cron hourly
0 0 * * * /path/to/docweb/cron/cron daily
0 0 * * 1 /path/to/docweb/cron/cron weekly
0 0 1 * * /path/to/docweb/cron/cron monthly
