+      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.
