RefTeX consists of eleven Lisp files.  It might not be a bad idea to put
them into their own directory.

That's where a separate ChangeLog file could make sense.  But I agree
that it would not be a good idea to put the whole ChangeLog from the
standalone version in there.  I'd have to check how much effort it would
be to write down the changes relative to the current version in Emacs.
It could be a bit of work. (c:

The ChangeLog is about 26 kB.  One could shave off a bit of it by
removing the entries related to the Makefiles.  Here is a link if you
want to have a look:

http://cvs.savannah.gnu.org/viewvc/reftex/ChangeLog?root=auctex&view=markup

If the log can take such amount of data, then I would be fine with it.
And besides that I'd prepare a shorter entry for the ChangeLog file.

Now that would be a nice solution.  RefTeX is currently maintained in a
CVS repository, though.  I'm not sure if this makes matters better or
worse.
