unzoo 4.4-5 (powerpc binary) in ubuntu feisty

 A zoo archive is a file that contains several files, called its members,
 usually in compressed form to save space. 'unzoo' can list all or selected
 members or extract all or selected members, i.e., uncompress them and write
 them to files. It cannot add new members or delete members. For this you need
 the zoo archiver, called 'zoo'.
