;; Enables the kill-ring to interact with the clipboard when running
;; Emacs from a Mac OSX terminal (without losing full kill-ring
;; functionality). All I did was modify xclip.el to work with pbcopy
;; and pbpaste. The real thanks go to Leo Shidai Liu, the author of
;; xclip.el.

Would you consider promoting this to a "regular" github repo? I'd love to include it in MELPA, and it would be nice if it had a proper home where fixes etc. could be submitted.

seconded! Found a repo here: https://github.com/jkp/pbcopy.el
