The archive contains a small snippet (update.c) to call a backup script (autobackup) once a week from within the update routine of a MUD. The autobackup script creates backups of several directories (Merc by default) and emails them (using mailx) to the provided address.

You'll need to set the version and email variables in the autobackup script. The code in update.c needs to be placed within a function that is called at least once an hour.
