 Usage: libremanage poweroff|poweron|reboot HOSTNAME|CHANNEL [BOARD_ID]
 
-BOARD_ID is not needed if only 1 relay device is connected.  To
-understand CHANNEL and BOARD_ID, run hidusb-relay-cmd and
-hidusb-relay-cmd state.

-Using a configuration (/etc/libremanage.conf) allows you to use HOSTNAME
-instead of CHANNEL and BOARD_ID.
+HOSTNAME is based on configuration in /etc/libremanage.conf.
 
 Note, the relay's channels default state when plugged in are off.
 
+Example config:
+
+# This config is sourced from bash, so make sure its valid bash.
+cephserver3_channel=1
+cephserver3_board_id=HURTM
+cephserver2_channel=2
+cephserver2_board_id=HURTM
+# end of config

+Example usage given the above config:

+libremanage reboot cephserver3

+BOARD_ID is not needed if only 1 relay device is connected, or if it is
