Subject: Script run from cron to regularly update the master ZFS copies of the
 ports and source trees.  Since we have >=1 consumer of these trees that run
 frequently but do not insist on up-to-the-second trees, it makes sense to
 "pre-update" them regularly and then then re-use in all of the consumers,
 instead of potentially doing several updates simultaneously or on demand. 
 Consumers can clone the ZFS snapshot into their local filesystem which takes
 a couple of seconds instead of minutes or tens of minutes for the CVS update.

We update to a date stamp instead of "." because this avoids
ambiguity of commits that happen while the tree update is in progress
(unfortunately it's slower).
