"""Broadcast copy program.

Multicast, actually.

The idea is that you point a server program at a file that you want to
publish, like this, and it gives you a magic cookie:

    $ bccpo.py backups.zip
    reading `backups.zip`...done.
    bccpi.py S3di2Dw39

Then you run the client program on another machine on the local net
with that same magic cookie, and it retrieves it:

    $ bccpi.py S3di2Dw39
    getting:
        backups.zip
    retrieved 1023853 bytes

Ideally the file transfer would be encrypted and verified with the
magic cookie. I’m starting with not.
