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

Versions are included for unix, pc, mac, and amiga systems.

This MIME implementation is intended to be as simple and portable as
possible.  For a slightly more sophisticated MIME implementation, see
the program MetaMail, available via anonymous FTP to
thumper.bellcore.com, in directory pub/nsb
