Usage:
$0 [-iIcChRSd:p:f:a] [test|testgroup] [...]

Options:
     [-h]      Show this message and exit.

     [-I|-i]   Turn off/on interactive tests. Default: on
               (overrides XDG_TEST_NO_INTERACTIVE)
  
     [-C|-c]   Turn off/on deletion of tempfiles. Default: on
               (overrides XDG_TEST_DONT_CLEANUP)

     [-R]      Turn off su to root tests.
	       You will not be prompted for the root password at the beginning of the testrun.

     [-S]      Use sudo instead of su.

     [-a]      Run all tests. (i.e xdg-*/) Has no effect if tests are specified explicitly.

     [-d dir]  Set XDG_TEST_DIR to dir

     [-p path] Reset PATH to path. Recommended for internal use only.

     [-f pid]  RESERVED -- state flag for self reference. DON'T USE.

Arguments:

After options, all arguments correspond to tests to run. The default is to run all tests, which consist of all files matching 'xdg-*/t.*'.

Supplied testgroups can be a list of directories or a list of individual tests.
