#@ Author : David Ligeret
#@ Reason : Initial release
#@---------------------------------------------------
#@ Date   : 20080821
#@ Author : David Ligeret
#@ Reason : Add verbose mode
#@---------------------------------------------------
#@ Date   : 20090219
#@ Author : Joshua Daniel Franklin
#@ Reason : Add try/except to catch AuthError and CIMError
#@---------------------------------------------------
#@ Date   : 20100202
#@ Author : Branden Schneider
#@ Reason : Added HP Support (HealthState)
#@---------------------------------------------------
#@ Date   : 20100512
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Combined different versions (Joshua and Branden)
#@ Reason : Added hardware type switch (dell or hp)
#@---------------------------------------------------
#@ Date   : 20100626/28
#@ Author : Samir Ibradzic www.brastel.com
#@ Reason : Added basic server info
