#  ClickingsGTKArray.py  (c) Kari Laitinen

#  2009-02-11  Last modification.

#  This program works in the same way as programs ClickingsGTK.py
#  and ClickingsApplet.java.

#  In this version of the program the Python lists are used
#  in the same way as, for example, Java arrays. Thus this
#  version may be easier to understand for those people
#  who are familiar with ClickingsApplet.java.
