    (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.")

of S-expression data.  The typical example of this would be Lisp or Scheme
source code.

ParEdit helps **keep parentheses balanced** and adds many keys for moving
S-expressions and moving around in S-expressions.  Its behavior can be jarring
for those who may want transient periods of unbalanced parentheses, such as
when typing parentheses directly or commenting out code line by line.")
