The basic syntax is:</p> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-shell" data-lang="shell"><span style="display:flex;"><span>$&gt; python validate.py &lt; file_to_validate.html </span></span></code></pre></div><p>It requires <a href="http://www.aaronsw.com/2002/html2text/">html2text</a> to print the detailed list of errors.</p>
