I admit that I don't grok setup's code either.  But if the parser
already handles such a tag (which IMO should be replaces: with a
lower-case r, just like other tags), then it should be straightforward.
 The goal is for an install on such a package to trigger an uninstall on
all packages listed in replaces:, similar to how requires: triggers an
install, except that the former is not recursive.

Unfortunately that's as much as I can contribute at the moment, with my
lack of understanding of the code involved.
