|  | 5 | Stores not just filenames but the files themselves in a balanced | 
|  | 6 | tree.  Uses journalling. |

|  | 8 | Balanced trees are more efficient than traditional file system |

|  | 11 | In general, ReiserFS is as fast as ext2, but is very efficient with | 
|  | 12 | large directories and small files.  Additional patches are needed |

|  | 16 | It is more easily extended to have features currently found in | 
|  | 17 | database and keyword search systems than block allocation based file | 
|  | 18 | systems are.  The next version will be so extended, and will support | 
|  | 19 | plugins consistent with our motto ``It takes more than a license to | 
|  | 20 | make source code open.'' |

|  | 35 | possibly imagine of its internal consistency throughout its |

|  | 38 | latest benchmarks.:-) Use of this option allows our team to go all | 
|  | 39 | out in checking for consistency when debugging without fear of its | 
|  | 40 | effect on end users.  If you are on the verge of sending in a bug | 
|  | 41 | report, say Y and you might get a useful error message.  Almost |
