;; This package provides GNU Emacs major modes for editing C, C++,

;; CC Mode supports K&R and ANSI C, ANSI C++, Objective-C, Java,
-;; CORBA's IDL, and Pike with a consistent indentation model across
-;; all modes. This indentation model is intuitive and very flexible,
-;; so that almost any desired style of indentation can be supported.

;; CC Mode's immediate ancestors were, c++-mode.el, cplus-md.el, and

-;; NOTE: This mode does not perform font-locking (a.k.a syntactic
-;; coloring, keyword highlighting, etc.) for any of the supported
-;; modes. Typically this is done by a package called font-lock.el
-;; which we do *not* maintain. You should contact the Emacs or XEmacs
