# Mathieu Jobin - 2009-02-04 - GPL
# 2006.05.16 : First version QtRuby 3
#              goal was to be a kicker applet but QtRuby was not ready at the time so I made a main window.
# 2008-12-28 : imported code into svn
# 2009-02-04 : Debut port to plasma
# 2009-02-06 : First working stable version (missing is the resize event, a timer, a config dialog and a plasma app icon)
#/usr/bin/env ruby -w
