I actually emailed Walter before writing this code, asking him if he 
could add a way to get the latest version. He suggested I do that 
instead.

In the real code there's also a fallback checking a file on my website 
that is supposed to contain the latest version number, but I'm not 
really keeping it up to date since this hack hasn't failed me yet.
