New port: anacron
Anacron is a periodic command scheduler. It executes
commands at intervals specified in days. Unlike cron, it
does not assume that the system is running continuously.
It can therefore be used to control the execution of daily,
weekly and monthly jobs (or anything with a period of n
days), on systems that don't run 24 hours a day.
Anacron is not an attempt to make cron redundant.
