No, he meant the very useful function os.path.join(), which is more
intelligent than a simple string join.

For instance, it ignores empty arguments, and if one of the arguments starts
at the root dir again ("/home", "scarblac", "/home") it throws away the
arguments before that. If one of the arguments ends with a path seperator, a
new one isn't inserted.

The documentation talks about inserting a /, but it actually means inserting
whatever seperator is relevant on the current platform.
