;;; Commentary:
;; This package also provides rectangle support with *visible rectangle*
;; highlighting, which is similar with cua-mode rectangle support. But it is
;; lighter weight and uses iedit mechanisms.
;; The code was developed and fully tested on Gnu Emacs 24.0.93, partially
;; tested on Gnu Emacs 22. If you have any compatible problem, please let me
;; know.
