Yay, thanks Jim. So nice to see these random items I wrote down so many
years ago being worked on :). The main reason I wanted to compare the
two is just so we could say "latexrefman incorporates all of latex-info"
[and a lot more]. Don't forget to update the NEWS at some point :).

By the way, I don't think there's a reason to do @samp{@file{...}}.
Just @samp{...} (for quotes) or @file{...} (no quotes) seems enough.
At least, that is the normal Texinfo convention. -k
