Subject: [PATCH] This is a trivial command line utility to print MD5
checksums. I published it on the web as http://www.python.org/2.1/md5sum.py
so I thought I might as well check it in.
Works with Python 1.5.2 and later.
Works like the Linux tool ``mdfsum file ...'' except it doesn't take
any options or read stdin.
