#! This is a script that will probably end up saving your ass more times
#! then you'll probably want to admit.  I wrote this back when I was co-deity
#! of the first empire tourney in December of 1990.  This is a basic script
#! run from cron usually 15 miniutes before the update and keeps three copies
#! of the binaries and empire data on hand in tared and compressed format.
#! If you run faster games increase the frequency of the calls from cron.
#! 45 7,15,23 * * * /home/evil/EMP/bin/saveass 
#! Above is a sample cron entry that does the backup three times a day.
#! This script should run on most all UNIX computers with all you'll have
#! to do is change the $BACKUPSDIR variable at the top.
