+# daily DCC cron job
+
+# This script should be run daily or more often when there is a shortage
+#   of disk space to run dbclean to discard and compress old checksums.
+#   It also discards old DCC client log files.
+
+#.  By default it is installed in @libexecdir@.  Instead of being copied
+#   to a directory such as /etc/cron/daily on some systems, a symbolic link
+#   should be used.
+
+# cron tab entry like this can be used:
+# 15	2	*	*	*	@libexecdir@/cron-dccd
+#   It is best to choose different times for each of your DCC servers so
+#   that your servers are not all busy cleaning their databases at once.
+
+#   -x	    turn on debugging
+#   -F	    do not follow symbolic links because they are used to share
+#		per-user directories
+#   -h dir  override DCC home directory @prefix@
+#   -a args for dbclean in addition to DBCLEAN_ARGS in @prefix@/dcc_conf
