   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.
