# Purpose of this module is to export the locally built mapscript module
# prior to installation, do some name normalization that allows testing of
# the so-called next generation class names, and define some classes 
# useful to many test cases.
#
# All test case modules should import mapscript from testing
#
#     from testing import mapscript
