+     "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.")
