We have a bit of code for the help menu item that actually does call
$BROWSER.  We basically assume that calling $BROWSER $URL will open
the URL in the browser, and let the browser take care of figuring out
the type and stuff.

We'd have to be a little more security conscious that the help stuff
-- it simply uses system(), which causes shell interpretation.  We'd
want  to use exec() or a variant to make sure there's no evail shell
manipulation causing other things to be run.
