   7 # This gateway retrieves the output of "show run" command (or its
   8 # equivalent) and prints it onto stdout. When run, it accepts the
   9 # following commands on stdin:
  10 #
  11 # * get8021q <endpoint> <handler> <outputfile>
  12 #   (save remote config text into provided local file)
  13 #
  14 # * getcdpstatus <endpoint> <handler> <outputfile>
  15 #   (save remote status text into provided local file)
  16 #
  17 # * deploy <endpoint> <handler> <inputfile>
  18 #   (execute given text in privileged mode)
