Description: ext2, minix and xiafs filesystem defragmenter
  As a file system is used, data tends to become more and more
  scattered across the disk, degrading performance.  A disk
  defragmenter simply re-organises the data on the disk, so that
  individual files occupy a single sequential set of disk 
blocks,
  and all the free space on the disk is collected together in a
  single region. This generally means that reading a whole file
  is faster, and disk accesses in general are more efficient.

For the purposes of this utility, ext2 == ext3.
