=head1 NAME
mimeexplode - explode one or more MIME messages
=head1 SYNOPSIS
mimeexplode <mime-msg-file> <mime-msg-file> ...
someprocess | mimeexplode -
=head1 DESCRIPTION
Takes one or more files from the command line that contain MIME
messages, and explodes their contents out into subdirectories
of the current working directory. The subdirectories are
just called C<msg0>, C<msg1>, C<msg2>, etc. Existing directories are
skipped over.
The message information is output to the stdout, like this:
Message: msg3 (inputfile1.msg)
Part: msg3/filename-1.dat (text/plain)
Part: msg3/filename-2.dat (text/plain)
Message: msg5 (input-file2.msg)
Part: msg5/dir.gif (image/gif)
Part: msg5/face.jpg (image/jpeg)
Message: msg6 (infile3)
Part: msg6/filename-1.dat (text/plain)
This was written as an example of the MIME:: modules in the
MIME-parser package I wrote. It may prove useful as a quick-and-dirty
way of splitting a MIME message if you need to decode something, and
you don't have a MIME mail reader on hand.
