  84
  85 testlist argument is a list of tests in the form of <test dir>/<test name>.
  86
  87 <test dir> is a directory under tests that contains a group file,
  88 with a list of the names of the tests in that directory.
  89
  90 <test name> may be either a specific test file name (e.g. xfs/001) or
  91 a test file name match pattern (e.g. xfs/*).
  92
  93 group argument is either a name of a tests group to collect from all
  94 the test dirs (e.g. quick) or a name of a tests group to collect from
  95 a specific tests dir in the form of <test dir>/<group name> (e.g. xfs/quick).
  96 If you want to run all the tests in the test suite, use "-g all" to specify all
  97 groups.
  98
  99 exclude_file argument refers to a name of a file inside each test directory.
 100 for every test dir where this file is found, the listed test names are
 101 excluded from the list of tests to run from that test dir.
 102
 103 external_file argument is a path to a single file containing a list of tests
 104 to exclude in the form of <test dir>/<test name>.
