| | 15 | + * Allow to build rules to find files and directories. |
| | 16 | + * |
| | 17 | + * All rules may be invoked several times, except for ->in() method. |
| | 18 | + * Some rules are cumulative (->name() for example) whereas others are destructive |
| | 19 | + * (most recent value is used, ->maxdepth() method for example). |
| | 20 | + * |
| | 21 | + * All methods return the current sfFinder object to allow easy chaining: |

| | 23 | + * $files = sfFinder::type('file')->name('*.php')->in(.); |
| | 24 | + * |
| | 25 | + * Interface loosely based on perl File::Find::Rule module. |
