is there code that sends the contents of a directory as a multi-part mime message to e-mail recipients?

Found this on Python Library Reference section 12.2.10 Examples (under 
the email module)
     #!/usr/bin/env python
     """Send the contents of a directory as a MIME message.
     Usage: dirmail [options] from to [to ...]*
     Options:
         -h / --help
             Print this message and exit.
         -d directory
         --directory=directory
             Mail the contents of the specified directory, otherwise use 
the
             current directory.  Only the regular files in the directory 
are sent,
             and we don't recurse to subdirectories.
     `from' is the email address of the sender of the message.
     `to' is the email address of the recipient of the message, and 
multiple
     recipients may be given.
     The email is sent by forwarding to your local SMTP server, which 
then does the
     normal delivery process.  Your local machine must be running an 
SMTP server.
