Log Message:
test suite script for the W3C markup validator
(and in longer term, to compare validators) 
This work is an evolution from earlier work on the Link Test Suite ( http://dev.w3.org/cvsweb/2008/link-testsuite/ )
with a number of small differences:
* instead of a nested directory structure, the test suite is described in a single XML file
* comparison of results and expected results are more flexible, e.g it is possible to specify
  "results should have some warning(s)" rather than "results should have 12 warnings exactly"
* easy selection of the tested validator instance from the command line
* possibility of running only a subset of the test suite with a commandline option

Run or Generate test suite for markup validator(s)

Usage: harness.py [options] [run|sanity|doc]
        -h, --help: this manual you are reading
        -v, --verbose: verbose output
        -q, --quiet: suppress all output except errors
        --validator_uri: use a specific validator instance
          e.g http://validator.w3.org/check
        --id=collection_id: run a single collection from the test suite
          In run mode only, this filters the test suite and uses only
          a collection identified with id="..." 
          with its children tests and collections
        run: run the test suite 
        sanity: check that this code is still working 
            useful after using test cases or modifying code
