# This checks HeaderTest's in each module.  A HeaderTest can be found in the
# module 'test' directory in a file otb<module_name>HeaderTest.cxx.  This
# contains a null main(), but includes all the classes in the module.  The
# primary purpose of this test is to make sure there are not missing module
# dependencies.

# This does not force the developer to install python to be able to build OTB.
# The tests will simply not be run if python is unavailable.
