#!/usr/bin/env ruby
# == Synopsis
# This script validates an HTML page via HTTP and checks for broken
# links and images. Links are followed one step away from the start page.
# HTML validation is also done for pages linked internally from the start page
# (i.e. relative URLs).
#
# == Usage
# vendor/plugins/html_test/script/validate http://my.url.com [options]
#
# Options:
#
# --no-follow::                 Don't follow any anchor or images URLs on
#                               the start page (i.e. only one page is requested).
#
# --validators validator_list:: A comma separated list of validators to use
#                               for HTML validation. Supported validators:
#                               tidy, xmllint, w3c. Default validator is
#                               tidy if it is installed, otherwise w3c.
#
# --dtd dtd_path::              Path to the DTD file to use for xmllint
#                               validation. By default xmllint will use
#                               the XHTML 1.0 strict DTD. Set dtd_path
#                               to "doctype" to make xmllint use the
#                               DTD specified in the DOCTYPE tag
#                               (can be slow).
#
# --skip skip_patterns::        A comma separated list of regexp patterns for
#                               URLs to not visit. Using the pattern '.*'
#                               is equivalent to the --no-follow option.
#
# --only only_pattern::         Only visit URLs matching given regexp pattern
#
# --no-external::               Do not visit external URLs, i.e. URLs with
#                               different domain than the start page.
#
# --quiet::                     Don't output anything unless there is a failure.
