-      GNU Emacs is an extensible, customizable text editor—and more.  At its
-      core is an interpreter for Emacs Lisp, a dialect of the Lisp
-      programming language with extensions to support text editing.
-
-      The features of GNU Emacs include: content-sensitive editing modes,
-      including syntax coloring, for a wide variety of file types including
-      plain text, source code, and HTML; complete built-in documentation,
-      including a tutorial for new users; full Unicode support for nearly all
-      human languages and their scripts; highly customizable, using Emacs
-      Lisp code or a graphical interface; a large number of extensions that
-      add other functionality, including a project planner, mail and news
-      reader, debugger interface, calendar, and more.  Many of these
-      extensions are distributed with GNU Emacs; others are available
-      separately.
-
-      This is "Mac port" addition to GNU Emacs 24. This provides a native
-      GUI support for Mac OS X 10.4 - 10.11. Note that Emacs 23 and later
-      already contain the official GUI support via the NS (Cocoa) port for
-      Mac OS X 10.4 and later. So if it is good enough for you, then you
-      don't need to try this.
