[XeTeX] XeTeX and arbitrary page sizes?

[Stephen Moye]

I need to put something on a page generally called half-letter: 5.5in by
8.5in. How can I tell XeTeX to do this? The -papersize=legal:landscape
option works like a charm, by the way.

One other, perhaps slightly frivolous, question: How is `XeTeX' pronounced?
I start to tell people about it and am stopped dead in my tracks when I
attempt to say its name. The embarrassment is more than I can stand...;>}
