+mcron
+# From package info:
+# > Homepage: http://www.gnu.org/software/mcron
+# > Description: Guile-based program for running jobs at regular times
+# > The GNU package mcron (Mellor's cron) can be a 100% compatible replacement for
+# > Vixie cron (though the Debian package is not configured this way). 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.

+dstat
+# From package info:
+# > Dstat is a versatile replacement for vmstat, iostat and ifstat. Dstat
