        (AWSY) tests.

        awsy-test is implemented as a marionette test and marionette
        test arguments also apply although they are not necessary
        since reasonable defaults will be chosen.

        The AWSY specific arguments can be found in the Command
        Arguments for AWSY section below.

        awsy-test will automatically download the tp5n.zip talos
        pageset from tooltool and install it under
        topobjdir/_tests/awsy/html. You can specify your own page set
        by specifying --web-root and --page-manifest.

        The results of the test will be placed in the results
        directory specified by the --results argument.

        On Windows, you may experience problems due to path length
        errors when extracting the tp5n.zip file containing the
        test pages or when attempting to write checkpoints to the
        results directory. In that case, you should specify both
        the --web-root and --results arguments pointing to a location
        with a short path. For example:

        --web-root=c:\\\\tmp\\\\html --results=c:\\\\tmp\\\\results

        Note that the double backslashes are required.
