Yeah, I didn't think there would be.  As I said, emacs.info is
supposed to be included in the emacs package.

Interesting.  There is no /usr/share/info/doc file at all?  What
does info show you when you run just "info" from the command line,
without specifying a subject?

I'm running Fedora 21, which shouldn't be much different from
Centos.  To me, this looks like a packaging error on Centos' part.
So far as I know, /usr/share/info/doc has to be there; it's the
top-level info node.  (I could be wrong, of course; if so, I hope
someone more knowledgeable will jump in here.)
