Re: [Rubycocoa-talk] Documentation for RubyCocoa on Leopard (with followup KVC/CoreData question).

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Thanks Eloy and Axel.
One quick question: when I follow Axel's instructions to install from the
tar, am I re-installing the whole RubyCocoa framework, or am I just
installing the docs? I assume it just installs the docs, but I want to make
sure.

Thanks,

-Rich-
