/*
* Runs one test file from the ES5 test suite test-262
* Usage: mujs <this-file> [-s ] [-f] [-l file1.js -l ...] suit-root test-file
* -s: print test source on failure
* -f: print full paths/stacktraces if possible
* -l: load a js file after the harness and before the test (to override things)
*
* If there are errors, print them and exits with code 1, else exit code is 0.
*
* The test suite is at: https://github.com/tc39/test262.git
* The ES5 suite is at branch "es5-tests"
*
* - The test suite throws on any error, possibly with info at ex.message .
* - Some tests make irreversible changes to global attrubutes, therefore it's
* required to run each test file in a new mujs instance.
