USAGE = '''\
%(program)s -- Test script for DOM implementations.

usage: %(program)s [-h] [implementations...]

Parameters:
    -g      Use the Tkinter GUI from unittestgui, if available.

    -h      Print this help text.

    -x      Treat the list of tests as tests to exclude rather than include.

    tests   List of tests to execute.  By default, all known testcases are run.
            Known tests include:

            - DOM          the basic DOM
            - ParsedXML    the persistent/wrapped Zope DOM
            - Printer      the DOM-to-XML Printer
            - Parser       the Expat parser and DOM builder
            - Persistence  persistence of the managed DOM
            - Truthable    checks for truth tests
            - Acquisition  checks for acquisition-related integrity failure
