%description
LZ4 compression for Java, based on Yann Collet’s work available at
http://code.google.com/p/lz4/.

This library provides access to two compression methods that both generate a
valid LZ4 stream:
• fast scan (LZ4):
  - low memory footprint (~ 16 KB),
  - very fast (fast scan with skipping heuristics in case the input looks
    incompressible),
  - reasonable compression ratio (depending on the redundancy of the input).
• high compression (LZ4 HC):
  - medium memory footprint (~ 256 KB),
  - rather slow (~ 10 times slower than LZ4),
  - good compression ratio (depending on the size and the redundancy of the
    input).

The streams produced by those 2 compression algorithms use the same compression
format, are very fast to decompress and can be decompressed by the same
decompressor instance.
