Sorry if this has been asked before, but ...

While 1.8.1 contains the 'ri' main program and runtime (and RDoc
extensions), it doesn't seem to include the documentation for builtin
classes (i.e. the *.c files).  Furthermore, my laptop is a Machine of
Very Little Brain, and running 'rdoc --ri lib/*' takes a very long time,
and a few randomly sampled files didn't seem to have any RDoc comments
in them.

The last version of 'ri' that actually provides documentation is
ri-1.8b.tgz, which claims to be a test version and produces the warning
"don't put space before argument parentheses".  So, my questions are:

1. Where do I find the latest/final documentation for 1.8.1 builtins in
'ri' format, or suitable for processing by the 1.8.1 rdoc/ri?

2. How much of the 1.8 library (including extensions) has RDoc comments
and/or pregenerated 'ri' files?

3. *Can* I run rdoc on *.c files, and expect a meaningful result?

I'm still getting used to Ruby, and I depend on 'ri' to find the Ruby
Way.  Pointers to an earlier discussion, or direct answers, would be
appreciated.

Thanks in advance.
