 4# This example script retrieves the DHCP state of a given interface.
 5# In the interest of keeping the KVP daemon code free of distro specific
 6# information; the kvp daemon code invokes this external script to gather
 7# DHCP setting for the specific interface.
 8#
 9# Input: Name of the interface
10#
11# Output: The script prints the string "Enabled" to stdout to indicate
12#	that DHCP is enabled on the interface. If DHCP is not enabled,
13#	the script prints the string "Disabled" to stdout.
14#
15# Each Distro is expected to implement this script in a distro specific
16# fashion. For instance, on Distros that ship with Network Manager enabled,
17# this script can be based on the Network Manager APIs for retrieving DHCP
18# information.
