39 .SH DESCRIPTION
40 .I GNU Emacs
41 is a version of
42 .IR Emacs ,
43 written by the author of the original (PDP-10)
44 .IR Emacs ,
45 Richard Stallman.
46 .br
47 The primary documentation of GNU Emacs is in the GNU Emacs Manual,
48 which you can read using Info, either from Emacs or as a standalone
49 program.
50 Please look there for complete and up-to-date documentation.
51 This man page is updated only when someone volunteers to do so; the
52 Emacs maintainers' priority goal is to minimize the amount of time
53 this man page takes away from other more useful projects.
54 .br
55 The user functionality of GNU Emacs encompasses
56 everything other
57 .I Emacs
58 editors do, and it is easily extensible since its
59 editing commands are written in Lisp.
60 .PP
61 .I Emacs
62 has an extensive interactive help facility,
63 but the facility assumes that you know how to manipulate
64 .I Emacs
65 windows and buffers.
66 CTRL-h or F1 enters the Help facility.
67 Help Tutorial (CTRL-h t) starts an interactive tutorial which can
68 teach beginners the fundamentals of
69 .I Emacs
70 in a few minutes.
71 Help Apropos (CTRL-h a) helps you
72 find a command given its functionality, Help Character (CTRL-h c)
73 describes a given character's effect, and Help Function (CTRL-h f)
74 describes a given Lisp function specified by name.
75 .PP
76 .IR Emacs 's
77 Undo can undo several steps of modification to your buffers, so it is
78 easy to recover from editing mistakes.
79 .PP
80 .IR "GNU Emacs" 's
81 many special packages handle mail reading (RMail) and sending (Mail),
82 outline editing (Outline), compiling (Compile), running subshells
83 within
84 .I Emacs
85 windows (Shell), running a Lisp read-eval-print loop
86 (Lisp-Interaction-Mode), automated psychotherapy (Doctor), and much more.
87 .PP
88 There is an extensive reference manual, but
89 users of other Emacses
90 should have little trouble adapting even
91 without a copy.
92 Users new to
93 .I Emacs
94 will be able
95 to use basic features fairly rapidly by studying the tutorial and
96 using the self-documentation features.
97 .

227 .\" START DELETING HERE IF YOU'RE NOT USING X
228 .SS Using Emacs with X
229 .I Emacs
230 has been tailored to work well with the X window system.
231 If you run
232 .I Emacs
233 from under X windows, it will create its own X window to
234 display in.
235 You will probably want to start the editor as a background
236 process so that you can continue using your original window.
237 .PP
238 .I Emacs
239 can be started with the following X switches:
240 .RS
241 .TP 8
242 .BI \-\-name " name"
243 Specify the name which should be assigned to the initial
244 .I Emacs
245 window.
246 This controls looking up X resources as well as the window title.
247 .TP
248 .BI \-T " name\fR,\fP " \-\-title " name"
249 Specify the title for the initial X window.
250 .TP
251 .BR \-r ", " \-rv ", " \-\-reverse\-video
252 Display the
253 .I Emacs
254 window in reverse video.
255 .TP
256 .BI \-fn " font\fR,\fP " \-\-font " font"
257 Set the
258 .I Emacs
259 window's font to that specified by
260 .IR font .
261 You will find the various
262 .I X
263 fonts in the
264 .I /usr/lib/X11/fonts
265 directory.
266 Note that
267 .I Emacs
268 will only accept fixed width fonts.
269 Under the X11 Release 4 font-naming conventions, any font with the
270 value "m" or "c" in the eleventh field of the font name is a fixed
271 width font.
272 Furthermore, fonts whose name are of the form
273 .IR width x height
274 are generally fixed width, as is the font
275 .IR fixed .
276 See
277 .BR xlsfonts (1)
278 for more information.
279
280 When you specify a font, be sure to put a space between the
281 switch and the font name.

299 .BI \-ib " pixels\fR,\fP " \-\-internal\-border " pixels"
300 Set the window's internal border width to the number of pixels specified

306 Set the
307 .I Emacs
308 window's width, height, and position as specified.
309 The geometry specification is in the standard X format; see

311 for more information.
312 The width and height are specified in characters; the default is
313 80 by 24.
314 See the Emacs manual, section "Options for Window Size and Position",
315 for information on how window sizes interact
316 with selecting or deselecting the tool bar and menu bar.

659 .SH BUGS
660 There is a mailing list, bug-gnu-emacs@gnu.org, for reporting Emacs
661 bugs and fixes.
662 But before reporting something as a bug, please try to be sure that
663 it really is a bug, not a misunderstanding or a deliberate feature.
664 We ask you to read the section ``Reporting Emacs Bugs'' near the
665 end of the reference manual (or Info system) for hints on how and
666 when to report bugs.
667 Also, include the version number of the Emacs you are running in
668 \fIevery\fR bug report that you send in.
669
670 Do not expect a personal answer to a bug report.
671 The purpose of reporting bugs is to get them fixed for everyone
672 in the next release, if possible.
673 For personal assistance, look in the SERVICE file (see above) for
674 a list of people who offer it.
675
676 Please do not send anything but bug reports to this mailing list.
677 For more information about Emacs mailing lists, see the
678 file /usr/local/emacs/etc/MAILINGLISTS.
679 Bugs tend actually to be fixed if they can be isolated, so it is
680 in your interest to report them in such a way that they can be
681 easily reproduced.
