+      The GNU package mcron (Mellor's cron) is a 100% compatible
+      replacement for Vixie cron.  It is written in pure Guile, and
+      allows configuration files to be written in scheme (as well as
+      Vixie's original format) for infinite flexibility in specifying
+      when jobs should be run.  Mcron was written by Dale Mellor.
