   1 # This plugin provides a wrapper around the "wakeonlan" tool available from most
   2 # distributions' package repositories, or from the following website:
   3 #
   4 # http://gsd.di.uminho.pt/jpo/software/wakeonlan/
   5 #
   6 # In order to use this wrapper, create the ~/.wakeonlan directory, and place in
   7 # that directory one file for each device you would like to be able to wake. Give
   8 # the file a name that describes the device, such as its hostname. Each file
   9 # should contain a line with the mac address of the target device and the network
  10 # broadcast address.
  11 #
  12 # For instance, there might be a file ~/.wakeonlan/leto with the following
  13 # contents:
  14 #
  15 # 00:11:22:33:44:55:66 192.168.0.255
  16 #
  17 # To wake that device, use the following command:
  18 #
  19 # # wake leto
  20 #
  21 # The available device names will be autocompleted, so:
  22 #
  23 # # wake <tab>
  24 #
  25 # ...will suggest "leto", along with any other configuration files that were
  26 # placed in the ~/.wakeonlan directory.
  27 #
  28 # For more information regarding the configuration file format, check the
  29 # wakeonlan man page.
