zoo 2.10-21 (powerpc binary) in ubuntu lucid

 Zoo is used to create and maintain collections of files in compressed
 form. It uses a Lempel-Ziv compression algorithm that gives space
 savings in the range of 20% to 80% depending on the type of file data.
 Zoo can store and selectively extract multiple generations of the same
 file.
 .
 This package exists for its historical value. If you are looking for
 a compression tool for serious use, check tar and gzip.
