- ;;; Commentary:
-
- ;; This package provides GNU Emacs major modes for editing C, C++,
- ;; Objective-C, Java and IDL code. As of the latest Emacs and XEmacs
- ;; releases, it is the default package for editing these languages.
- ;; This package is called "CC Mode", and should be spelled exactly
- ;; this way. It supports K&R and ANSI C, ANSI C++, Objective-C, Java,
- ;; and CORBA's IDL 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.
- ;; Installation, usage, and programming details are contained in an
- ;; accompanying texinfo manual.
-
- ;; CC Mode's immediate ancestors were, c++-mode.el, cplus-md.el, and
- ;; cplus-md1.el..
-
- ;; 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 I do *not* maintain. You should contact the Emacs
- ;; maintainers for questions about coloring or highlighting in any
- ;; language mode.
-
- ;; To submit bug reports, type "C-c C-b". These will be sent to
- ;; bug-gnu-emacs@prep.ai.mit.edu as well as cc-mode-help@python.org,
- ;; and I'll read about them there (the former is mirrored as the
- ;; Usenet newsgroup gnu.emacs.bug). Questions can sent to
- ;; help-gnu-emacs@prep.ai.mit.edu (mirrored as gnu.emacs.help) and/or
- ;; cc-mode-help@python.org. Please do not send bugs or questions to
- ;; my personal account.
-
- ;; Many, many thanks go out to all the folks on the beta test list.
- ;; Without their patience, testing, insight, code contributions, and
- ;; encouragement CC Mode would be a far inferior package.
-
- ;; You can get the latest version of CC Mode, including PostScript
- ;; documentation and separate individual files from:
- ;;
- ;; http://www.python.org/ftp/emacs/
-
- ;; Or if you don't have access to the World Wide Web, through
- ;; anonymous ftp from:
