  <para>
   Loads a font for later use. Before text is output with a loaded font it
   must be set with <function>ps_setfont</function>. This function needs the
   adobe font metric file in order to calculate the space used up by the
   characters. A font which is loaded within a page will only be available on
   that page. Fonts which are to be used in the complete document has to be
   loaded before the first call of <function>ps_begin_page</function>. Calling
   <function>ps_findfont</function> between pages will make that font
   available for all following pages.

      <para>
       <function>ps_findfont</function> will try to load the file passed in
       the parameter <parameter>encoding</parameter>. Encoding files are of
       the same syntax as those used by <command>dvips(1)</command>. They
       contain a font encoding vector (which is currently not used but must be
       present) and a list of extra ligatures to extend the list of ligatures
       derived from the afm file.
      </para>
      <para>
       <parameter>encoding</parameter> can be &null; or the empty string if
       the default encoding (TeXBase1) shall be used.
      </para>
      <para>If the encoding is set to <literal>builtin</literal> then there
      will be no reencoding and the font specific encoding will be used. This
      is very useful with symbol fonts.
