   9 -- statusd_dgs.lua: Check for moves waiting on www.dragongoserver.net
  10 --
  11 -- This monitor will check your status page on www.dragongoserver.net
  12 -- for games waiting on a move.  Simply add %dgs to the statusd
  13 -- template, and set a login and password.
  14 --
  15 -- In all honesty, I'd be surprised if there are more than a couple of
  16 -- people who might use this script -- the intersection of go players
  17 -- (and dgs users at that) and ion users can't be that large.
  18 --
  19 -- TO USE: Put %dgs in the template in cfg_statusbar.lua (e.g.,
  20 -- "dgs:% %dgs") and  set the login and password.  Something like:
  21 --
  22 -- dgs={
  23 --     login = "mylogin",
  24 --     password = "ABCxyz",
  25 -- },
  26 --
  27 -- in  mod_statusbar.launch_statusd.
  28 --
  29 -- NOTE: the wget command is used to fetch the status page and the
  30 -- account info is passed on the command line.  This means that you need
  31 -- wget for this monitor to work, and that your account info (including
  32 -- password) will be available on your local system via ps.  If that
  33 -- concerns you, don't use this script -- or provide a patch.  :)
  34 --
  35 -- BUG: Occasionally get_moves returns nil because it gets no output
  36 -- from the wget.  This is either because I'm not using io.popen()
  37 -- properly (I don't have docs for it) or, perhaps, a bug elsewhere.
  38 -- When this happens you'll see a ? (with the critical hint set) instead
  39 -- of a number for waiting moves.
