d for any specific problem space.
 Megatest in of itself does not know what constitutes a PASS or FAIL of
 a test.
 In most cases megatest is best used in conjunction with logpro or a similar
 tool to parse, analyze and decide on the test outcome.
 A call to megatest can then be made to record the result.
