title: Identifying a standard gettext pot file
body: <p>Within my php framework (CakePHP), is a i18n tool for generating POT files. The header of the file is generated like so:</p>
  
  <pre><code>protected function _writeHeader() {
      $output = "# LANGUAGE translation of CakePHP Application\n";
      $output .= "# Copyright YEAR NAME &lt;EMAIL@ADDRESS&gt;\n";
      $output .= "#\n";
      $output .= "#, fuzzy\n";
      $output .= "msgid \"\"\n";
      $output .= "msgstr \"\"\n";
      $output .= "\"Project-Id-Version: PROJECT VERSION\\n\"\n";
      $output .= "\"POT-Creation-Date: " . date("Y-m-d H:iO") . "\\n\"\n";
      $output .= "\"PO-Revision-Date: YYYY-mm-DD HH:MM+ZZZZ\\n\"\n";
      $output .= "\"Last-Translator: NAME &lt;EMAIL@ADDRESS&gt;\\n\"\n";
      $output .= "\"Language-Team: LANGUAGE &lt;EMAIL@ADDRESS&gt;\\n\"\n";
      $output .= "\"MIME-Version: 1.0\\n\"\n";
      $output .= "\"Content-Type: text/plain; charset=utf-8\\n\"\n";
      $output .= "\"Content-Transfer-Encoding: 8bit\\n\"\n";
      $output .= "\"Plural-Forms: nplurals=INTEGER; plural=EXPRESSION;\\n\"\n\n";
      return $output;
  }
  </code></pre>
  
  <p>I am curious to know if the following:</p>
  
  <pre><code>$output .= "#, fuzzy\n";
  $output .= "msgid \"\"\n";
  $output .= "msgstr \"\"\n";
  </code></pre>
  
  <p>breaks some sort of standards of gettext. If it does not, I would love an explanation as to why one would put that in the header of the file.</p>
