+-- original code made by Bzed and published on http://awesome.naquadah.org/wiki/Calendar_widget
+-- modified by Marc Dequènes (Duck) <Duck@DuckCorp.org> (2009-12-29), under the same licence,
+-- and with the following changes:
+--   + transformed to module
+--   + the current day formating is customizable
+-- modified by Jörg Thalheim (Mic92) <jthalheim@gmail.com> (2011), under the same licence,
+-- and with the following changes:
+--   + use tooltip instead of naughty.notify
+--   + rename it to cal
+--   + lua52 compliant module
+--
+-- 1. require it in your rc.lua
+--	require("cal")
+-- 2. attach the calendar to a widget of your choice (ex mytextclock)
+--	cal.register(mytextclock)
+--    If you don't like the default current day formating you can change it as following
+--	cal.register(mytextclock, "<b>%s</b>") -- now the current day is bold instead of underlined
+--
+-- # How to Use #
+-- Just hover with your mouse over the widget, you register and the calendar popup.
+-- On clicking or by using the mouse wheel the displayed month changes.
+-- Pressing Shift + Mouse click change the year.
