p7zip 9.04~dfsg.1-1 (ia64 binary) in ubuntu karmic

 p7zip is the Unix port of 7-Zip, a file archiver that archives with
 very high compression ratios.
 .
 p7zip provides:
  - /usr/bin/7zr
    a standalone minimal version of the 7-zip tool that only handles
    7z archives. 7z compression is 30-50% better than ZIP compression.
  - /usr/bin/p7zip
    a gzip like wrapper around 7zr.
 .
 p7zip-full provides 7z and 7za which support more compression formats.
