;; ccc.el - Proof General for the Casl Consistency Checker
;;
;; Author: Christoph Lüth <cxl@informatik.uni-bremen.de>
;;
;; This is a fairly straightforward instantiation of Proof General for
;; the Casl Consistency Checker, CCC.
;;
;; CASL is the standard algebraic specification language, and CCC is a
;; tool to check consistency of CASL specifications.
;;
;; For more information, hasten thee browser yonder:
