Files and Pipes
---------------

   mh-e does offer a couple of commands that are not a part of MH.  The
first one, `C-o' (`mh-write-msg-to-file'), writes a message to a file
(think of the `o' as in "output").  You are prompted for the filename.
If the file already exists, the message is appended to it.  You can
also write the message to the file without the header by specifying a
prefix argument (such as `C-u C-o /tmp/foobar RET').  Subsequent writes
to the same file can be made with the `!' command.

   You can also pipe the message through a Unix shell command with the
`|' (`mh-pipe-msg') command.  You are prompted for the Unix command
through which you wish to run your message.  If you give an argument to
this command, the message header is included in the text passed to the
command (the contrived example `C-u | lpr' would be done with the `l'
command instead).

   If the message is a shell archive `shar' or has been run through
`uuencode' use `M-n' (`mh-store-msg') to extract the body of the
message.  The default directory for extraction is the current
directory, and you have a chance to specify a different extraction
directory.  The next time you use this command, the default directory is
the last directory you used.
