Just do an automatic check against the gem's listing on Rubyforge, and
make sure it's an open source license. If so, then you're free to put the
docs on your site (assuming you agree with the license yourself), and you
don't have to pay attention to the author's wishes in contradiction with
the license at all. (However, you may choose to do so as a courtesey.)
Open source does not (necessarily) mean freely modifiable. Please be
sure that if you do this, that the licenses you check for are
compatible with CC S/A, not all will be.
