"""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.
