+       rc-update -d|del script [runlevel1 ...]
+       rc-update -s|show [runlevel1 ...]
+
+examples:
+       # rc-update add net.eth0 default
+       Adds the net.eth0 script (in /etc/init.d) to the "default" runlevel.
+
+       # rc-update del sysklogd
+       Deletes the sysklogd script from all runlevels.  The original script
+       is not deleted, just any symlinks to the script in /etc/runlevels/*.
+
+       # rc-update del net.eth2 default wumpus
+       Delete the net.eth2 script from the default and wumpus runlevels.
+       All other runlevels are unaffected.  Again, the net.eth2 script
+       residing in /etc/init.d is not deleted, just any symlinks in
+       /etc/runlevels/default and /etc/runlevels/wumpus.
+
+       # rc-update show
+       Show all the available scripts and list at which runlevels they
+       will execute.
