Comment(by dports@…):

 Replying to [comment:1 idoadam@…]:
 > Aaccording to the official Emacs.app web site (http://emacs-
 app.sourceforge.net/), emacs actually supersedes Emacs.app and the Cocoa
 version can be built by the --with-ns switch in configure (this is
 supported by the documentation in the gnustep directory in the official
 emacs23.1 tarball).

 The emacs.app port *is* emacs 23.1 with --with-ns. I suppose it's
 confusing that the port lists http://emacs-app.sourceforge.net/ as its
 homepage; maybe it shouldn't anymore.

 I think it is appropriate for these to remain separate ports, both because
 they install into very different locations (/Applications vs $prefix) and
 because people may want to have both installed.

 >Additionally, the Carbon variant is slightly different and is not
 superseded by Emacs.app either.

 My understanding is that the Carbon port has been discontinued and
 deprecated. Am I mistaken?
