/**
 * The general (non-delivery engine) function to parse the configuration .ini file
 *
 * @param string $configPath The directory to load the config file from.
 *                           Default is Max's /var directory.
 * @param string $configFile The configuration file name (eg. "geotargeting").
 *                           Default is no name (ie. the main Max
 *                           configuration file).
 * @param boolean $sections  Process sections, as per parse_ini_file().
 * @param string  $type      The config file type value (eg. ".php"). Allows BC
 *                           support for old ".ini" files.
 *
 * @return mixed The array resulting from the call to parse_ini_file(), with
 *               the appropriate .php file for the installation.
