37 ;; This package provides GNU Emacs major modes for editing C, C++,
38 ;; Objective-C, Java, CORBA's IDL, Pike and AWK code. As of the
39 ;; latest Emacs and XEmacs releases, it is the default package for
40 ;; editing these languages. This package is called "CC Mode", and
41 ;; should be spelled exactly this way.
43 ;; CC Mode supports K&R and ANSI C, ANSI C++, Objective-C, Java,
44 ;; CORBA's IDL, Pike and AWK with a consistent indentation model
45 ;; across all modes. This indentation model is intuitive and very
46 ;; flexible, so that almost any desired style of indentation can be
47 ;; supported. Installation, usage, and programming details are
48 ;; contained in an accompanying texinfo manual.
50 ;; CC Mode's immediate ancestors were, c++-mode.el, cplus-md.el, and
53 ;; To submit bug reports, type "C-c C-b". These will be sent to
54 ;; bug-gnu-emacs@gnu.org (mirrored as the Usenet newsgroup
55 ;; gnu.emacs.bug) as well as bug-cc-mode@gnu.org, which directly
56 ;; contacts the CC Mode maintainers. Questions can sent to
57 ;; help-gnu-emacs@gnu.org (mirrored as gnu.emacs.help) and/or
58 ;; bug-cc-mode@gnu.org. Please do not send bugs or questions to our
59 ;; personal accounts; we reserve the right to ignore such email!
61 ;; Many, many thanks go out to all the folks on the beta test list.
62 ;; Without their patience, testing, insight, code contributions, and
63 ;; encouragement CC Mode would be a far inferior package.
65 ;; You can get the latest version of CC Mode, including PostScript
66 ;; documentation and separate individual files from:
68 ;; http://cc-mode.sourceforge.net/
70 ;; You can join a moderated CC Mode announcement-only mailing list by
