+.SH NAME
+emacs \- GNU project Emacs
+.
+.
+.SH SYNOPSIS
+.B emacs
+[
+.I command-line switches
+] [
+.I files ...\&
+]
+.
+.
+.SH DESCRIPTION
+.I GNU Emacs
+is a version of
+.IR Emacs ,
+written by the author of the original (PDP-10)
+.IR Emacs ,
+Richard Stallman.
+.br
+The primary documentation of GNU Emacs is in the GNU Emacs Manual,
+which you can read using Info, either from Emacs or as a standalone
+program.
+Please look there for complete and up-to-date documentation.
+This man page is updated only when someone volunteers to do so; the
+Emacs maintainers' priority goal is to minimize the amount of time
+this man page takes away from other more useful projects.
+.br
+The user functionality of GNU Emacs encompasses
+everything other
+.I Emacs
+editors do, and it is easily extensible since its
+editing commands are written in Lisp.
+.PP
+.I Emacs
+has an extensive interactive help facility,
+but the facility assumes that you know how to manipulate
+.I Emacs
+windows and buffers.
+CTRL-h or F1 enters the Help facility.
+Help Tutorial (CTRL-h t) starts an interactive tutorial which can
+teach beginners the fundamentals of
+.I Emacs
+in a few minutes.
+Help Apropos (CTRL-h a) helps you
+find a command given its functionality, Help Character (CTRL-h c)
+describes a given character's effect, and Help Function (CTRL-h f)
+describes a given Lisp function specified by name.
+.PP
+.IR Emacs 's
+Undo can undo several steps of modification to your buffers, so it is
+easy to recover from editing mistakes.
+.PP
+.IR "GNU Emacs" 's
+many special packages handle mail reading (RMail) and sending (Mail),
+outline editing (Outline), compiling (Compile), running subshells
+within
+.I Emacs
+windows (Shell), running a Lisp read-eval-print loop
+(Lisp-Interaction-Mode), automated psychotherapy (Doctor), and much more.
+.PP
+There is an extensive reference manual, but
+users of other Emacses
+should have little trouble adapting even
+without a copy.
+Users new to
+.I Emacs
+will be able
+to use basic features fairly rapidly by studying the tutorial and
+using the self-documentation features.
+.

+.\" START DELETING HERE IF YOU'RE NOT USING X
+.SS Using Emacs with X
+.I Emacs
+has been tailored to work well with the X window system.
+If you run
+.I Emacs
+from under X windows, it will create its own X window to
+display in.
+You will probably want to start the editor as a background
+process so that you can continue using your original window.
+.PP
+.I Emacs
+can be started with the following X switches:
+.RS
+.TP 8
+.BI \-\-name " name"
+Specify the name which should be assigned to the initial
+.I Emacs
+window.
+This controls looking up X resources as well as the window title.
+.TP
+.BI \-T " name\fR,\fP " \-\-title " name"
+Specify the title for the initial X window.
+.TP
+.BR \-r ", " \-rv ", " \-\-reverse\-video
+Display the
+.I Emacs
+window in reverse video.
+.TP
+.BI \-fn " font\fR,\fP " \-\-font " font"
+Set the
+.I Emacs
+window's font to that specified by
+.IR font .
+You will find the various
+.I X
+fonts in the
+.I /usr/lib/X11/fonts
+directory.
+Note that
+.I Emacs
+will only accept fixed width fonts.
+Under the X11 Release 4 font-naming conventions, any font with the
+value "m" or "c" in the eleventh field of the font name is a fixed
+width font.
+Furthermore, fonts whose name are of the form
+.IR width x height
+are generally fixed width, as is the font
+.IR fixed .
+See
+.BR xlsfonts (1)
+for more information.
+
+When you specify a font, be sure to put a space between the
+switch and the font name.
+.TP
+.BI \-\-xrm " resources"
+Set additional X resources.
+.TP
+.BI "\-\-color\fR,\fP \-\-color=" mode
+Override color mode for character terminals;
+.I mode
+defaults to `auto', and can also be `never', `auto', `always',
+or a mode name like `ansi8'.
+.TP
+.BI \-bw " pixels\fR,\fP " \-\-border\-width " pixels"
+Set the
+.I Emacs
+window's border width to the number of pixels specified by
+.IR pixels .
+Defaults to one pixel on each side of the window.
+.TP
+.BI \-ib " pixels\fR,\fP " \-\-internal\-border " pixels"
+Set the window's internal border width to the number of pixels specified
+by
+.IR pixels .
+Defaults to one pixel of padding on each side of the window.
+.TP
+.BI \-g " geometry\fR,\fP " \-\-geometry " geometry"
+Set the
+.I Emacs
+window's width, height, and position as specified.
+The geometry specification is in the standard X format; see
+.BR X (7)
+for more information.
+The width and height are specified in characters; the default is
+80 by 24.
+See the Emacs manual, section "Options for Window Size and Position",
+for information on how window sizes interact
+with selecting or deselecting the tool bar and menu bar.
+.TP
+.BI \-lsp " pixels\fR,\fP " \-\-line\-spacing " pixels"
+Additional space to put between lines.
+.TP
+.BR \-vb ", " \-\-vertical\-scroll\-bars

+.SH MANUALS
+You can order printed copies of the GNU Emacs Manual from the Free
+Software Foundation, which develops GNU software.
+See the file ORDERS for ordering information.
+.br
+Your local Emacs maintainer might also have copies available.
+As with all software and publications from FSF, everyone is permitted
+to make and distribute copies of the Emacs manual.
+The TeX source to the manual is also included in the Emacs source
+distribution.
+.
+.
+.SH FILES
+/usr/local/share/info \(em files for the Info documentation browser.
+The complete text of the Emacs reference manual is included in a
+convenient tree structured form.
+Also includes the Emacs Lisp Reference Manual, useful to anyone
+wishing to write programs in the Emacs Lisp extension language.
+
+/usr/local/share/emacs/$VERSION/lisp \(em Lisp source files and
+compiled files that define most editing commands.
+Some are preloaded; others are autoloaded from this directory when
+used.
+
+/usr/local/libexec/emacs/$VERSION/$ARCH \(em various programs that are
+used with GNU Emacs.
+
+/usr/local/share/emacs/$VERSION/etc \(em various files of information.
+
+/usr/local/share/emacs/$VERSION/etc/DOC.* \(em contains the documentation
+strings for the Lisp primitives and preloaded Lisp functions
+of GNU Emacs.
+They are stored here to reduce the size of Emacs proper.
+
+/usr/local/share/emacs/$VERSION/etc/SERVICE lists people offering
+various services to assist users of GNU Emacs, including education,
+troubleshooting, porting and customization.
+.
+.
+.SH BUGS
+There is a mailing list, address@hidden, for reporting Emacs
+bugs and fixes.
+But before reporting something as a bug, please try to be sure that
+it really is a bug, not a misunderstanding or a deliberate feature.
+We ask you to read the section ``Reporting Emacs Bugs'' near the
+end of the reference manual (or Info system) for hints on how and
+when to report bugs.
+Also, include the version number of the Emacs you are running in
+\fIevery\fR bug report that you send in.
+
+Do not expect a personal answer to a bug report.
+The purpose of reporting bugs is to get them fixed for everyone
+in the next release, if possible.
+For personal assistance, look in the SERVICE file (see above) for
+a list of people who offer it.
+
+Please do not send anything but bug reports to this mailing list.
+For more information about Emacs mailing lists, see the
+file /usr/local/emacs/etc/MAILINGLISTS.
+Bugs tend actually to be fixed if they can be isolated, so it is
+in your interest to report them in such a way that they can be
+easily reproduced.
+.
+.
+.SH UNRESTRICTIONS
+.I Emacs
+is free; anyone may redistribute copies of
+.I Emacs
+to
+anyone under the terms stated in the
+.I Emacs
+General Public License,
+a copy of which accompanies each copy of
+.I Emacs
+and which also
+appears in the reference manual.
+.PP
+Copies of
+.I Emacs
+may sometimes be received packaged with distributions of Unix systems,
+but it is never included in the scope of any license covering those
+systems.
+Such inclusion violates the terms on which distribution is permitted.
+In fact, the primary purpose of the General Public License is to
+prohibit anyone from attaching any other restrictions to
+redistribution of
+.IR Emacs .
+.PP
+Richard Stallman encourages you to improve and extend
+.IR Emacs ,
+and urges that
+you contribute your extensions to the GNU library.
+Eventually GNU (Gnu's Not Unix) will be a complete replacement
+for Unix.
+Everyone will be free to use, copy, study and change the GNU system.
