No, mcron at the user-level is even simpler, simply tweak your configuration
file and start `mcron`.

Example job in ~/.config/cron/job.guile:
--8<---------------cut here---------------start------------->8---
(job '(next-hour (range 0 24 3)) "updatedb")
--8<---------------cut here---------------end--------------->8---

Once mcron is running, you can test the schedule by calling `mcron --schedule=5`
to list the 5 next scheduled jobs.

Have a look at "(mcron) Top", it's a very short read ;)
