if test "$1" = "--version"; then

Run all tests, update files in log/ of that directory and display the 
results.

The exit value is a bitwise OR:

  Bit 0 set: One or more tests failed
  Bit 1 set: Bail out detected (one or more test scripts aborted)

  That is:

    0: Everything ok
    1: One or more tests failed
    2: One or more scripts aborted
    3: Tests failed and scripts aborted

Lines starting with "# NOTICE:" are displayed during the run. They don't 
affect the exit value, so they can for example be used to inform the 
user that tests have been skipped.

Usage: $progname testname [options] [testname [...]]

Options:

  -h, --help
    Show this help.
  --version
    Print version information.
