 class PowerMan:
 	"""Python wrapper for calling powerman commands
 
 	This class makes calls to a powerman deamon for a cluster of computers.
 	The make-up of such a call looks something like:
 		$ pm -h elssd1:10101 <option> <node>
 	where option is something like --off, --on, --cycle and where node is 
 	elssd8, or whatever values are setup in powerman.conf.  Note that powerman
 	itself must be configured for this fence agent to work.
