Usage: %(progName)s [options] [profile.tests]

Options:
  -h, --help                Show this message
  -t regexp, --tests=regexp Run only matching tests (can be used more
                            than once)
  -x regexp, --exclude-tests=regexp Exclude matching tests (can be used
                            more than once)
Example:
  %(progName)s tests/all.tests
  %(progName)s -t basic tests/all.tests results/all
         Run all tests whose path contains the word 'basic'

  %(progName)s -t ^glean/ -t tex tests/all.tests results/all
         Run all tests that are in the 'glean' group or whose path contains
		 the substring 'tex'
