# user had installed.

# Version 1.3 (8/19/10) (CMake 2.8.3)
# Included patch by Simone Rossetto to check if either Python or Perl
# are present in the system. Whichever intepreter that is detected
# is now used to run the test generator program. If both interpreters
# are detected, the CXXTEST_USE_PYTHON variable is obeyed.
#
# Also added support for CXXTEST_TESTGEN_ARGS, for manually specifying
# options to the CxxTest code generator.
# Version 1.2 (3/2/08)
# Included patch from Tyler Roscoe to have the perl & python binaries
# detected based on CXXTEST_INCLUDE_DIR
