# Description:  Analyse program source and make test stubs add to the

#
# Date          Change
# -----------------------------------------------------------------------------
# 14/08/2003    Version 1
# 06/02/2005    Returned to make more OO and usable - need to create a test
#               and check it into the test suite in one go!
# 28/08/2005    Added method: run
# 15/10/2005    Created test file: TestMakerTest.tpm
