Comparing current (out of date) working copy with HEAD in repository

This question was posed by someone working with me who returned from a 2
week vacation. He wants to know how the working copy on his machine can be
compared with the current state of the repository. The best I can think of
is to do a checkout to a different directory, and then compare the 2 working
copies. Is there a more efficient way of doing this?

Note: I would prefer a solution using TortoiseSVN, though I am also
interested in a more general solution using Subversion, which is why I'm
cross posting this message.

Thanks in advance,
