   5 # This is a set of Python widgets, built on top of pythonTk.  They are
   6 # designed to be highly customizable, flexible, and useful.  They are
   7 # also all built from the base PythonTk widgets so no other external
   8 # libraries are needed.
   9 #
  10 # Use it in good health.  It's hereby released under the GPL, if you
  11 #  have questions about the GPL contact the Free Software Foundation.
