Showing private methods in RDoc?

Looking at the RDoc output generated by my Rails app, I
don't see any entries for private methods.  Is this just
an artifact of that way that RDoc is being used in Rails
or is this an intrinsic limitation to the program?

If it's the latter, I'd like to suggest that it be made
into an option, so that developers can view their private
methods.  After all, they can view the method calls in
RDoc, so the API isn't being hidden.  Also, they can see
the source code to the methods, outside of RDoc.

More generally, I'd be happy to hear about pointers to
documentation on the design and use of RDoc.
