[Rd] S4 documentation

1. promptClass generated a file that included
No methods defined with class "mspathDistributedCalculator" in the
Yet there are such methods.  Is this a not-working yet feature, or is
something funny going on (maybe I have definitions in the library and in
the global workspace...)?

2. Is the \code{\link{myS4class-class}} the proper way to
cross-reference a class?  \code{\link{myS4method-method}} the right way
to refer to a method?  I looked for something like \class or \method to
correspond to \code, but didn't see anything.

3.  This question goes beyond documentation.  I have been approaching
things like this:
setClass("A", ....)
foo <- function(a) ....
setClass("B", ...)
setMethod("foo", "B", ....)
so the first foo turns into the default function for the generic.

This was primarily motivated by discovering that
setMethod("foo", "A") where I have the first function definition
produced an error.

Is this a reasonable way to proceed?

Then do I document the generic with standard function documentation for
foo?  Are there some examples I could look at?  When I want to refer to
the function generically, how do I do that?

I'm using R 2.2.1, and I've found the documentation on documenting S4 a
bit too brief (even after looking at the recommended links, which in
some cases don't have much on documentation).  Since the docs say it's a
work in progress, I'm hoping to get the latest word here.
