This is the full system path to the location of the Smarty core
files. If not defined, Smarty will default this constant to the
internals/ sub-directory below
SMARTY_DIR.
If defined, the path must end with a slash/.
Use this constant when manually including any of the core.* files.
Example 11.2. SMARTY_CORE_DIR
<?php
// load core.get_microtime.php
require_once(SMARTY_CORE_DIR . 'core.get_microtime.php');
?>
