# Temporary script to test the HTML5 parser until it is able to
# run enough LayoutTests so that we know what changes we'll need
# to make to run-webkit-tests to support testing with the new parser.

# NOTE: This script is a total hack and should be rolled into
# run-webkit-tests instead of being improved further.
