  <para>
   This method is used to add a PHP bootstrap loader stub to a new Phar archive, or
   to replace the loader stub in an existing Phar archive.
  </para>
  <para>
   The loader stub for a Phar archive is used whenever an archive is included directly
   as in this example:
  </para>
  <programlisting role="php">
   <![CDATA[
<?php
include 'myphar.phar';
?>
   ]]>
  </programlisting>
  <para>
   The loader is not accessed when including a file through the <literal>phar</literal>
   stream wrapper like so:
  </para>
  <programlisting role="php">
   <![CDATA[
<?php
include 'phar://myphar.phar/somefile.php';
?>
   ]]>
  </programlisting>
