     "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.")

    (description
     "Geiser is a collection of Emacs major and minor modes that
conspire with one or more Scheme interpreters to keep the Lisp Machine
Spirit alive.  It draws inspiration (and a bit more) from environments
such as Common Lisp’s Slime, Factor’s FUEL, Squeak or Emacs itself, and
does its best to make Scheme hacking inside Emacs (even more) fun.

Or, to be precise, what i consider fun.  Geiser is thus my humble
contribution to the dynamic school of expression, and a reaction against
what i perceive as a derailment, in modern times, of standard Scheme
towards the static camp.  Because i prefer growing and healing to poking
at corpses, the continuously running Scheme interpreter takes the center
of the stage in Geiser.  A bundle of Elisp shims orchestrates the dialog
between the Scheme interpreter, Emacs and, ultimately, the schemer,
giving her access to live metadata.")
