  <para>

   as a comment in the header of the PostScript file. If the document is
   converted to pdf this fields will also be used for the document
   information.
  </para>
  <para>
   The <literal>BoundingBox</literal> is usually set to the value given to the
   first page. This only works if <function>ps_findfont</function> has not
   been called before. In such cases the BoundingBox would be left unset
   unless you set it explicitly with this function.
  </para>
  <para>
   This function will have no effect anymore when the header of the postscript
   file has been already written. It must be called before the first page
   or the first call of <function>ps_findfont</function>.
