37 | ;; This package provides GNU Emacs major modes for editing C, C++, | |
d9e94c22 MS |
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. | |
0ec8351b BW |
42 | |
43 | ;; CC Mode supports K&R and ANSI C, ANSI C++, Objective-C, Java, | |
d9e94c22 MS |
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. | |
785eecbb RS |
49 | |
50 | ;; CC Mode's immediate ancestors were, c++-mode.el, cplus-md.el, and | |
51 | ;; cplus-md1.el.. | |
52 | ||
785eecbb | 53 | ;; To submit bug reports, type "C-c C-b". These will be sent to |
0ec8351b BW |
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 | |
130c507e GM |

61 | ;; Many, many thanks go out to all the folks on the beta test list. |
62 | ;; Without their patience, testing, insight, code contributions, and | |
