  26. Stores not just filenames but the files themselves in a balanced

  28. Balanced trees are more efficient than traditional file system
  29. architectural foundations.
  30. In general, ReiserFS is as fast as ext2, but is very efficient with
  31. large directories and small files. Additional patches are needed
  32. for NFS and quotas, please see <http://www.namesys.com/> for links.
  33. It is more easily extended to have features currently found in
  34. database and keyword search systems than block allocation based file
  35. systems are. The next version will be so extended, and will support
  36. plugins consistent with our motto ``It takes more than a license to
  37. make source code open.''
