/**
*
* This is a port of sfFinder from the symfony-project.
* http://www.symfony-project.com
*
* Allow to build rules to find files and directories.
*
* All rules may be invoked several times, except for ->in() method.
* Some rules are cumulative (->name() for example) whereas others are destructive
* (most recent value is used, ->maxDepth() method for example).
*
* All methods return the current Doctrine_FileFinder object to allow easy chaining:
*
* $files = Doctrine_FileFinder::type('file')->name('*.php')->in(.);
*
* Interface loosely based on perl File::Find::Rule module.
