|
||
;; This package provides GNU Emacs major modes for editing C, C++,
|
||
;; Objective-C, Java, CORBA's IDL, Pike and AWK 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.
|
||
|
||
;; CC Mode supports K&R and ANSI C, ANSI C++, Objective-C, Java,
|
||
;; CORBA's IDL, Pike and AWK 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..
|
||
|
||
;; To submit bug reports, type "C-c C-b". These will be sent to
|
||
;; bug-gnu-emacs@gnu.org (mirrored as the Usenet newsgroup
|
||
;; gnu.emacs.bug) as well as bug-cc-mode@gnu.org, which directly
|
||
;; contacts the CC Mode maintainers. Questions can sent to
|
||
;; help-gnu-emacs@gnu.org (mirrored as gnu.emacs.help) and/or
|
||
;; bug-cc-mode@gnu.org. Please do not send bugs or questions to our
|
||
;; personal accounts; we reserve the right to ignore such email!
|
||
|
||
;; 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.
