this no longer holds true.

I propose to merge the code examples (this one and the ones on line 80 & 89):

The location is the only mandatory criteria. It tells the finder which
directory to use for the search::

    $finder->in(__DIR__);

    // search in several locations
    $finder->in(array(__DIR__, '/elsewhere'));

$finder->files()->in(array(__DIR__, '/elsewhere'));
$finder->in(__DIR__)->in('/elsewhere');
