|
||
;;; Commentary:
|
||
|
||
;; This package provides GNU Emacs major modes for editing C, C++,
|
||
;; Objective-C, and Java 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, and
|
||
;; Java, 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.
|
||
|
||
;; YOU CAN IGNORE ALL BYTE-COMPILER WARNINGS. They are the result of
|
||
;; the cross-Emacsen support. GNU Emacs 19 (from the FSF), GNU XEmacs
|
||
;; 19 (formerly Lucid Emacs), and GNU Emacs 18 all do things
|
||
;; differently and there's no way to shut the byte-compiler up at the
|
||
;; necessary granularity. Let me say this again: YOU CAN IGNORE ALL
|
||
;; BYTE-COMPILER WARNINGS (you'd be surprised at how many people don't
|
||
;; follow this advice :-).
|
||
|
||
;; 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
|
||
