[offtopic] how to save attachments using ordinary `mail' program.

[Walter Tautz <wtautz@math.uwaterloo.ca>]

If I save a message that has an attachment I get a file:

  This message is in MIME format.  The first part should be readable text,
  while the remaining parts are likely unreadable without MIME-aware tools.
  Send mail to mime@docserver.cac.washington.edu for more info.

I can view it, but it saves incorrectly.
