There is something to be said for taking all of these functions,
including the original RSiteSearch, out of utils and putting them in
the new RSiteSearch package.  These are the sorts of things that will
get revised frequently, and this way (I think) we won't have to bother
whoever takes care of utils, which is part of the regular R
distribution.

I'm adding Spencer Graves to the cc list.  Maybe he is interested in
doing this.
