Usage: $0 [OPTIONS] [TESTS]

Options:
  -A		Use "cat -A" to print test output (only some tests)
  -c		Run integration tests on a cluster
  -C		Clean up when done by removing test state directory (see -V)
  -D		Show diff between failed/expected test output (some tests only)
  -e		Exit on the first test failure
  -H		No headers - for running single test with other wrapper
  -I <count>    Iterate tests <count> times, exiting on failure (implies -e, -N)
  -L            Print daemon logs on test failure (only some tests)
  -N		Don't print summary of tests results after running all tests
  -q		Quiet - don't show tests being run (still displays summary)
  -S <lib>      Use socket wrapper library <lib> for local integration tests
  -v		Verbose - print test output for non-failures (only some tests)
  -V <dir>	Use <dir> as test state directory
  -x		Trace this script with the -x option
  -X		Trace certain scripts run by tests using -x (only some tests)
