sub usage

$my_progname version $VER

Description:

Run various Aria related tests. Typically used via make test as a unittest.

Options
--help             Show this help and exit.
--abort-on-error   Abort at once in case of error.
--number-of-tests  Print the total number of tests and exit.
--run-tests=...    Test range that should be run. You can give just
                   one number, to start tests from this test, or a range.
                   For example 45..89. To run a specific test alone,
                   for example test 215, use --run-tests=215..215
                   Use this option with caution, because some of the tests
                   might depend on previous ones.
--start-from=...   Alias for --run-tests
--silent=...       Silent option passed to ma_test* tests ('$opt_silent')
--tmpdir=...       Store tests data in this directory (works for most tests)
--valgrind=...     Options for valgrind.
                   ('$opt_valgrind')
--verbose          Be more verbose. Will print each unittest on a line
                   and result after. This mode cannot be used with unit.pl
                   when running in normal unit test mode.
--version          Show version number and exit.
EOF
  exit(0);
