The shell script runs the tests and diffs stdout against v8.txt. Lines added/removed means tests were broken/fixed. Future work is to a) fix failing tests, and b) enable more tests. A number are disabled for various reasons and mjsunit subdirectories are currently skipped. Need to decide on a case-by-case basis what is and isn't relevant to us. At the moment about 430 tests are run of which approx. 80% pass.
