This perl module can be used for periodically executing perl subroutines. the dates and parameters for the subroutines to be called are specified with a format known as crontab entry (see manpage crontab(5) or documentation of schedule::cron).

the philosophy behind schedule::cron is to call subroutines periodically from within one single perl program instead of letting cron trigger several (possibly different) perl scripts. everything under one roof. furthermore schedule::cron provides mechanism to create crontab entries dynamically, which isn't that easy with cron.
