Sammanfattning: Added a link to a modified version that allows unbalanced parens.

Provides a modifier to major modes such that `
‘parenthesis’’-type characters usually stay balanced. Changes a number of key bindings in the current major mode:
* ``open parenthesis''-type keys (the exact keys depend on the major mode) insert both opening and closing characters, and ``close parenthesis''-type keys simply move to the nearest closing character (not necessarily matching the key typed). * Meta-``open'' and ``close'' are rebound to simply insert the corresponding character. * ``delete-left''-type keys skip over ``close parenthesis''-type characters and only delete them when they can delete a matching ``open parenthesis''-type character (a delete can be forced by giving the ``delete-left''-type key an argument -- i.e. with ctrl-u or something).
If the ``open parenthesis-type keys are given a numeric argument, they will wrap their open and close around that many items. For example, in lisp modes, if the point is at -!- in:
(if (null? x) -!-(printf 3) hi)
then ``Esc 2 ( will result in
(if (null? x) (-!-(printf 3) hi))
