  14 %description
  15 Lbzip2 is a Pthreads-based parallel bzip2/bunzip2 filter, passable to
  16 GNU tar with the --use-compress-program option.
  17
  18 It isn't restricted to regular files on input, nor output. Successful
  19 splitting for decompression isn't guaranteed, just very likely
  20 (failure is detected). Splitting in both modes and compression itself
  21 occur with an approximate 900k block size.
  22
  23 On an Athlon-64 X2 6000+, lbzip2 was 92% faster than standard bzip2
  24 when compressing, and 45% faster when decompressing (based on wall
  25 clock time).
  26
  27 Lbzip2 strives to be portable by requiring UNIX 98 APIs only, besides
  28 an unmodified libbz2.
