+<longdescription>
+  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 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.
