+--- Watch widget.
+-- Here is an example of simple temperature widget which will update each 15
+-- seconds implemented in two different ways.
+-- The first, simpler one, will just display the return command output
+-- (so output is stripped by shell commands).
+-- In the other example `sensors` returns to the widget its full output
+-- and it's trimmed in the widget callback function:
+--
+--     211             mytextclock,
+--     212             wibox.widget.textbox('  |  '),
+--     213             -- one way to do that:
+--     214             awful.widget.watch('bash -c "sensors | grep temp1"', 15),
+--     215             -- another way:
+--     216             awful.widget.watch('sensors', 15, function(widget, stdout)
+--     217               for line in stdout:gmatch("[^\r\n]+") do
+--     218                 if line:match("temp1") then
+--     219                   widget:set_text(line)
+--     220                   return
+--     221                 end
+--     222               end
