   -- plugins
   --   Numbers can be automatically colored according to their value. xmobar
   --   decides color based on a three-tier/two-cutoff system, controlled by
   --   command options:
   --     --Low sets the low cutoff
   --     --High sets the high cutoff
   --
   --     --low sets the color below --Low cutoff
   --     --normal sets the color between --Low and --High cutoffs
   --     --High sets the color above --High cutoff
   --
   --   The --template option controls how the plugin is displayed. Text
   --   color can be set by enclosing in <fc></fc> tags. For more details
   --   see http://projects.haskell.org/xmobar/#system-monitor-plugins.
