    // This will result in:

// As you may have guessed, ConfigEditor uses var_export on
    // the values before putting them to config.
    // But sotimes it is not desirable. E.g. I want to add a variable:
    // $cfg_cachedir = ROOTDIR.'/maincache';
    // So, everytime I include the config, $cfg_cachedir should be
    // evaluated into 'D:/some/path/maincache';

    // pass true in the 4th argument, telling that the value is
    // in RAW format.
