%description
LZO is a portable lossless data compression library written in ANSI C.
It implements a number of algorithms with the following features:
- Decompression is simple and *very* fast.
- Requires no memory for decompression.
- Compression is pretty fast.
- Requires 64 kB of memory for compression.
- Allows you to dial up extra compression at a speed cost in the
  compressor. The speed of the decompressor is not reduced.
- Includes compression levels for generating pre-compressed data which
  achieve a quite competitive compression ratio.
- There is also a compression level which needs only 8 kB for
  compression.
- Supports overlapping compression and in-place decompression.
- Algorithm is thread safe.
- Algorithm is lossless.
