You have an executable my-program in your home directory, which
you want to run every hour. Create a file job.vixie in directory
~/.cron with the following contents
0 * * * * my-program
then run the command mcron.
Alternatively (full compatibility with Vixie cron), set your
environment variable EDITOR to your favorite editor, run
crontab -e, put the above line into the edit buffer, save and
exit. For this to work the cron daemon must be already running
on your system, as root.
