mpack 1.6-1ubuntu1 (ia64 binary) in ubuntu breezy

tools for encoding/decoding MIME messages
 Mpack and munpack are utilities for encoding and decoding
 (respectively) binary files in MIME (Multipurpose Internet
 Mail Extensions) format mail messages. For compatibility
 with older forms of transferring binary files, the munpack
 program can also decode messages in split-uuencoded format.

 Instead of munpack, the package maintainer recommends the
 more versatile package uudeview.
