# exchange-bmc-os-info: Set OS and BMC (Baseboard Management Controller)
#			 parameters during system startup.
#
# version:	0.72
#
# Authors:	Charles Rose <charles_rose@dell.com>
#		Jordan Hargrave <jordan_hargrave@dell.com>
#
# Description:  Script to set OS information in the BMC; fetch BMC IP/URL
#		and set in the OS for use by other scripts/user.
#
#		BMC IP and URL are made available in /var/run/bmc-info
#
#		Example to launch BMC web-interface:
#		# . /var/run/bmc-info
#		# xdg-open $BMC_URL
#
#		See here for details:
#		https://fedoraproject.org/wiki/Features/AgentFreeManagement
#
# OEM Specific: OEM specific ipmi commands go in:
#		'oem_set_os_version' and 'oem_get_bmc_url'
