     "GNU Emacs is an extensible and highly customizable text editor.  It is
based on an Emacs Lisp interpreter with extensions for text editing.  Emacs
has been extended in essentially all areas of computing, giving rise to a
vast array of packages supporting, e.g., email, IRC and XMPP messaging,
spreadsheets, remote server editing, and much more.  Emacs includes extensive
documentation on all aspects of the system, from basic editing to writing
large Lisp programs.  It has full Unicode support for nearly all human
languages.")
