35 ;;; Commentary:
|
|
|
36
|
|
|
37 ;; This package provides GNU Emacs major modes for editing C, C++,
|
|
177
|
38 ;; Objective-C, Java and IDL code. As of the latest Emacs and XEmacs
|
|
165
|
39 ;; releases, it is the default package for editing these languages.
|
|
|
40 ;; This package is called "CC Mode", and should be spelled exactly
|
|
177
|
41 ;; this way. It supports K&R and ANSI C, ANSI C++, Objective-C, Java,
|
|
|
42 ;; and CORBA's IDL with a consistent indentation model across all
|
|
|
43 ;; modes. This indentation model is intuitive and very flexible, so
|
|
|
44 ;; that almost any desired style of indentation can be supported.
|
|
|
45 ;; Installation, usage, and programming details are contained in an
|
|
|
46 ;; accompanying texinfo manual.
|
|
165
|
47
|
|
|
48 ;; CC Mode's immediate ancestors were, c++-mode.el, cplus-md.el, and
|
|
|
49 ;; cplus-md1.el..
|
|
|
50
|
|
|
51 ;; NOTE: This mode does not perform font-locking (a.k.a syntactic
|
|
|
52 ;; coloring, keyword highlighting, etc.) for any of the supported
|
|
|
53 ;; modes. Typically this is done by a package called font-lock.el
|
|
|
54 ;; which I do *not* maintain. You should contact the Emacs
|
|
|
55 ;; maintainers for questions about coloring or highlighting in any
|
|
|
56 ;; language mode.
|
|
|
57
|
|
|
58 ;; To submit bug reports, type "C-c C-b". These will be sent to
|
|
|
59 ;; bug-gnu-emacs@prep.ai.mit.edu as well as cc-mode-help@python.org,
|
|
|
60 ;; and I'll read about them there (the former is mirrored as the
|
|
|
61 ;; Usenet newsgroup gnu.emacs.bug). Questions can sent to
|
|
|
62 ;; help-gnu-emacs@prep.ai.mit.edu (mirrored as gnu.emacs.help) and/or
|
|
|
63 ;; cc-mode-help@python.org. Please do not send bugs or questions to
|
|
|
64 ;; my personal account.
|
|
|
65
|
|
|
66 ;; Many, many thanks go out to all the folks on the beta test list.
|
|
|
67 ;; Without their patience, testing, insight, code contributions, and
|
|
|
68 ;; encouragement CC Mode would be a far inferior package.
