 > Any reason not to merge emacs-app into the emacs portfile as a subport?
 Seems like there's a lot of duplication between the two, and that ought to
 make it easier to maintain.

 It is useful to be able to install the console/X11 version, in addition to
 the Cocoa version of emacs.  Not sure if a subport allows both to be
 installed at the same time.
