# This sample classifies the Python keywords alphabetically, using the
# first letter of the keyword (i.e., ``and`` goes into ``a``, ``for``
# goes into ``f`` and so on):
#
#      * For each letter, adds a child to the treectrl root
#      * In each child of the root item, adds its corresponding keyword(s)
