> If you're using OS functions you should NOT bank on the slashes being
forward-slashes.  This is platform-specific behavior.  You should use
os.path.split() to get the elements of your path and do a "/".join() on
them.  Otherwise your code will break on Windows because the path will be
denoted with backslashes.
