E.g. llSubStringIndex(...) > -1 was converted into !~llSubStringIndex(...) which is incorrect. We even had a test case for it... with a wrong expected response file.
Bug report and test case by Sinha Hynes (thanks!)
This test suite has been in use for a long time now, in place of the obsolete and unmanageable testparser.py and testfuncs.py. It verifies the complete optimizer output to stdout and stderr, to ensure that the output matches the expectations.
See unit_tests/README.txt for more info.
