     This should be the full system path to the location of the Smarty core
     files. If not defined, Smarty will default this constant to the
     <emphasis>internals/</emphasis>
     sub-directory below
     <link linkend="constant.smarty.dir">SMARTY_DIR</link>.
     If defined, the path must end with a slash.
     Use this constant when manually including any of the core.* files.
