-The GNU Manifesto
-*****************
-
-What's GNU? GNU's Not Unix!
-============================
-
- GNU, which stands for GNU's Not Unix, is the name for the complete
-Unix-compatible software system which I am writing so that I can give it
-away free to everyone who can use it. Several other volunteers are
-helping me. Contributions of time, money, programs, and equipment are
-greatly needed.
-
- So far we have an Emacs text editor with Lisp for writing editor
-commands, a source level debugger, a yacc-compatible parser generator,
-a linker, and around 35 utilities. A shell (command interpreter) is
-nearly completed. A new portable optimizing C compiler has compiled
-itself and may be released this year. An initial kernel exists, but
-many more features are needed to emulate Unix. When the kernel and
-compiler are finished, it will be possible to distribute a GNU system
-suitable for program development. We will use TeX as our text
-formatter, but an nroff is being worked on. We will use the free,
-portable X window system as well. After this we will add a portable
-Common Lisp, an Empire game, a spreadsheet, and hundreds of other
-things, plus online documentation. We hope to supply, eventually,
-everything useful that normally comes with a Unix system, and more.
-
- GNU will be able to run Unix programs, but will not be identical to
-Unix. We will make all improvements that are convenient, based on our
-experience with other operating systems. In particular, we plan to
-have longer filenames, file version numbers, a crashproof file system,
-filename completion perhaps, terminal-independent display support, and
-perhaps eventually a Lisp-based window system through which several
-Lisp programs and ordinary Unix programs can share a screen. Both C
-and Lisp will be available as system programming languages. We will
-try to support UUCP, MIT Chaosnet, and Internet protocols for
-communication.
-
- GNU is aimed initially at machines in the 68000/16000 class with
-virtual memory, because they are the easiest machines to make it run
-on. The extra effort to make it run on smaller machines will be left
-to someone who wants to use it on them.
-
- To avoid horrible confusion, please pronounce the `G' in the word
-`GNU' when it is the name of this project.
-
-Why I Must Write GNU
-====================
-
- I consider that the golden rule requires that if I like a program I
-must share it with other people who like it. Software sellers want to
-divide the users and conquer them, making each user agree not to share
-with others. I refuse to break solidarity with other users in this
-way. I cannot in good conscience sign a nondisclosure agreement or a
-software license agreement. For years I worked within the Artificial
-Intelligence Lab to resist such tendencies and other inhospitalities,
-but eventually they had gone too far: I could not remain in an
-institution where such things are done for me against my will.
-
- So that I can continue to use computers without dishonor, I have
-decided to put together a sufficient body of free software so that I
-will be able to get along without any software that is not free. I
-have resigned from the AI lab to deny MIT any legal excuse to prevent
-me from giving GNU away.
-
-Why GNU Will Be Compatible With Unix
-====================================
-
- Unix is not my ideal system, but it is not too bad. The essential
-features of Unix seem to be good ones, and I think I can fill in what
-Unix lacks without spoiling them. And a system compatible with Unix
-would be convenient for many other people to adopt.
-
-How GNU Will Be Available
-=========================
-
- GNU is not in the public domain. Everyone will be permitted to
-modify and redistribute GNU, but no distributor will be allowed to
-restrict its further redistribution. That is to say, proprietary
-modifications will not be allowed. I want to make sure that all
-versions of GNU remain free.
-
-Why Many Other Programmers Want to Help
-=======================================
-
- I have found many other programmers who are excited about GNU and
-want to help.
-
- Many programmers are unhappy about the commercialization of system
-software. It may enable them to make more money, but it requires them
-to feel in conflict with other programmers in general rather than feel
-as comrades. The fundamental act of friendship among programmers is the
-sharing of programs; marketing arrangements now typically used
-essentially forbid programmers to treat others as friends. The
-purchaser of software must choose between friendship and obeying the
-law. Naturally, many decide that friendship is more important. But
-those who believe in law often do not feel at ease with either choice.
-They become cynical and think that programming is just a way of making
-money.
-
- By working on and using GNU rather than proprietary programs, we can
-be hospitable to everyone and obey the law. In addition, GNU serves as
-an example to inspire and a banner to rally others to join us in
-sharing. This can give us a feeling of harmony which is impossible if
-we use software that is not free. For about half the programmers I
-talk to, this is an important happiness that money cannot replace.
-
-How You Can Contribute
-======================
-
- I am asking computer manufacturers for donations of machines and
-money. I'm asking individuals for donations of programs and work.
-
- One consequence you can expect if you donate machines is that GNU
-will run on them at an early date. The machines should be complete,
-ready-to-use systems, approved for use in a residential area, and not
-in need of sophisticated cooling or power.
-
- I have found very many programmers eager to contribute part-time
-work for GNU. For most projects, such part-time distributed work would
-be very hard to coordinate; the independently-written parts would not
-work together. But for the particular task of replacing Unix, this
-problem is absent. A complete Unix system contains hundreds of utility
-programs, each of which is documented separately. Most interface
-specifications are fixed by Unix compatibility. If each contributor
-can write a compatible replacement for a single Unix utility, and make
-it work properly in place of the original on a Unix system, then these
-utilities will work right when put together. Even allowing for Murphy
-to create a few unexpected problems, assembling these components will
-be a feasible task. (The kernel will require closer communication and
-will be worked on by a small, tight group.)
-
- If I get donations of money, I may be able to hire a few people full
-or part time. The salary won't be high by programmers' standards, but
-I'm looking for people for whom building community spirit is as
-important as making money. I view this as a way of enabling dedicated
-people to devote their full energies to working on GNU by sparing them
-the need to make a living in another way.
-
-Why All Computer Users Will Benefit
-===================================
-
- Once GNU is written, everyone will be able to obtain good system
-software free, just like air.
-
- This means much more than just saving everyone the price of a Unix
-license. It means that much wasteful duplication of system programming
-effort will be avoided. This effort can go instead into advancing the
-state of the art.
-
- Complete system sources will be available to everyone. As a result,
-a user who needs changes in the system will always be free to make them
-himself, or hire any available programmer or company to make them for
-him. Users will no longer be at the mercy of one programmer or company
-which owns the sources and is in sole position to make changes.
-
- Schools will be able to provide a much more educational environment
-by encouraging all students to study and improve the system code.
-Harvard's computer lab used to have the policy that no program could be
-installed on the system if its sources were not on public display, and
-upheld it by actually refusing to install certain programs. I was very
-much inspired by this.
-
- Finally, the overhead of considering who owns the system software
-and what one is or is not entitled to do with it will be lifted.
-
- Arrangements to make people pay for using a program, including
-licensing of copies, always incur a tremendous cost to society through
-the cumbersome mechanisms necessary to figure out how much (that is,
-which programs) a person must pay for. And only a police state can
-force everyone to obey them. Consider a space station where air must
-be manufactured at great cost: charging each breather per liter of air
-may be fair, but wearing the metered gas mask all day and all night is
-intolerable even if everyone can afford to pay the air bill. And the
-TV cameras everywhere to see if you ever take the mask off are
-outrageous. It's better to support the air plant with a head tax and
-chuck the masks.
-
- Copying all or parts of a program is as natural to a programmer as
-breathing, and as productive. It ought to be as free.
-
-Some Easily Rebutted Objections to GNU's Goals
-==============================================
-
- "Nobody will use it if it is free, because that means they can't
- rely on any support."
-
- "You have to charge for the program to pay for providing the
- support."
-
- If people would rather pay for GNU plus service than get GNU free
-without service, a company to provide just service to people who have
-obtained GNU free ought to be profitable.
-
- We must distinguish between support in the form of real programming
-work and mere handholding. The former is something one cannot rely on
-from a software vendor. If your problem is not shared by enough
-people, the vendor will tell you to get lost.
-
- If your business needs to be able to rely on support, the only way
-is to have all the necessary sources and tools. Then you can hire any
-available person to fix your problem; you are not at the mercy of any
-individual. With Unix, the price of sources puts this out of
-consideration for most businesses. With GNU this will be easy. It is
-still possible for there to be no available competent person, but this
-problem cannot be blamed on distibution arrangements. GNU does not
-eliminate all the world's problems, only some of them.
-
- Meanwhile, the users who know nothing about computers need
-handholding: doing things for them which they could easily do
-themselves but don't know how.
-
- Such services could be provided by companies that sell just
-hand-holding and repair service. If it is true that users would rather
-spend money and get a product with service, they will also be willing
-to buy the service having got the product free. The service companies
-will compete in quality and price; users will not be tied to any
-particular one. Meanwhile, those of us who don't need the service
-should be able to use the program without paying for the service.
-
- "You cannot reach many people without advertising, and you must
- charge for the program to support that."
-
- "It's no use advertising a program people can get free."
-
- There are various forms of free or very cheap publicity that can be
-used to inform numbers of computer users about something like GNU. But
-it may be true that one can reach more microcomputer users with
-advertising. If this is really so, a business which advertises the
-service of copying and mailing GNU for a fee ought to be successful
-enough to pay for its advertising and more. This way, only the users
-who benefit from the advertising pay for it.
-
- On the other hand, if many people get GNU from their friends, and
-such companies don't succeed, this will show that advertising was not
-really necessary to spread GNU. Why is it that free market advocates
-don't want to let the free market decide this?
-
- "My company needs a proprietary operating system to get a
- competitive edge."
-
- GNU will remove operating system software from the realm of
-competition. You will not be able to get an edge in this area, but
-neither will your competitors be able to get an edge over you. You and
-they will compete in other areas, while benefitting mutually in this
-one. If your business is selling an operating system, you will not
-like GNU, but that's tough on you. If your business is something else,
-GNU can save you from being pushed into the expensive business of
-selling operating systems.
-
- I would like to see GNU development supported by gifts from many
-manufacturers and users, reducing the cost to each.
-
- "Don't programmers deserve a reward for their creativity?"
-
- If anything deserves a reward, it is social contribution.
-Creativity can be a social contribution, but only in so far as society
-is free to use the results. If programmers deserve to be rewarded for
-creating innovative programs, by the same token they deserve to be
-punished if they restrict the use of these programs.
-
- "Shouldn't a programmer be able to ask for a reward for his
- creativity?"
-
- There is nothing wrong with wanting pay for work, or seeking to
-maximize one's income, as long as one does not use means that are
-destructive. But the means customary in the field of software today
-are based on destruction.
-
- Extracting money from users of a program by restricting their use of
-it is destructive because the restrictions reduce the amount and the
-ways that the program can be used. This reduces the amount of wealth
-that humanity derives from the program. When there is a deliberate
-choice to restrict, the harmful consequences are deliberate destruction.
-
- The reason a good citizen does not use such destructive means to
-become wealthier is that, if everyone did so, we would all become
-poorer from the mutual destructiveness. This is Kantian ethics; or,
-the Golden Rule. Since I do not like the consequences that result if
-everyone hoards information, I am required to consider it wrong for one
-to do so. Specifically, the desire to be rewarded for one's creativity
-does not justify depriving the world in general of all or part of that
-creativity.
-
- "Won't programmers starve?"
-
- I could answer that nobody is forced to be a programmer. Most of us
-cannot manage to get any money for standing on the street and making
-faces. But we are not, as a result, condemned to spend our lives
-standing on the street making faces, and starving. We do something
-else.
-
- But that is the wrong answer because it accepts the questioner's
-implicit assumption: that without ownership of software, programmers
-cannot possibly be paid a cent. Supposedly it is all or nothing.
-
- The real reason programmers will not starve is that it will still be
-possible for them to get paid for programming; just not paid as much as
-now.
-
- Restricting copying is not the only basis for business in software.
-It is the most common basis because it brings in the most money. If it
-were prohibited, or rejected by the customer, software business would
-move to other bases of organization which are now used less often.
-There are always numerous ways to organize any kind of business.
-
- Probably programming will not be as lucrative on the new basis as it
-is now. But that is not an argument against the change. It is not
-considered an injustice that sales clerks make the salaries that they
-now do. If programmers made the same, that would not be an injustice
-either. (In practice they would still make considerably more than
-that.)
-
- "Don't people have a right to control how their creativity is
- used?"
-
- "Control over the use of one's ideas" really constitutes control over
-other people's lives; and it is usually used to make their lives more
-difficult.
-
- People who have studied the issue of intellectual property rights
-carefully (such as lawyers) say that there is no intrinsic right to
-intellectual property. The kinds of supposed intellectual property
-rights that the government recognizes were created by specific acts of
-legislation for specific purposes.
-
- For example, the patent system was established to encourage
-inventors to disclose the details of their inventions. Its purpose was
-to help society rather than to help inventors. At the time, the life
-span of 17 years for a patent was short compared with the rate of
-advance of the state of the art. Since patents are an issue only among
-manufacturers, for whom the cost and effort of a license agreement are
-small compared with setting up production, the patents often do not do
-much harm. They do not obstruct most individuals who use patented
-products.
-
- The idea of copyright did not exist in ancient times, when authors
-frequently copied other authors at length in works of non-fiction. This
-practice was useful, and is the only way many authors' works have
-survived even in part. The copyright system was created expressly for
-the purpose of encouraging authorship. In the domain for which it was
-invented--books, which could be copied economically only on a printing
-press--it did little harm, and did not obstruct most of the individuals
-who read the books.
-
- All intellectual property rights are just licenses granted by society
-because it was thought, rightly or wrongly, that society as a whole
-would benefit by granting them. But in any particular situation, we
-have to ask: are we really better off granting such license? What kind
-of act are we licensing a person to do?
-
- The case of programs today is very different from that of books a
-hundred years ago. The fact that the easiest way to copy a program is
-from one neighbor to another, the fact that a program has both source
-code and object code which are distinct, and the fact that a program is
-used rather than read and enjoyed, combine to create a situation in
-which a person who enforces a copyright is harming society as a whole
-both materially and spiritually; in which a person should not do so
-regardless of whether the law enables him to.
-
- "Competition makes things get done better."
-
- The paradigm of competition is a race: by rewarding the winner, we
-encourage everyone to run faster. When capitalism really works this
-way, it does a good job; but its defenders are wrong in assuming it
-always works this way. If the runners forget why the reward is offered
-and become intent on winning, no matter how, they may find other
-strategies--such as, attacking other runners. If the runners get into
-a fist fight, they will all finish late.
-
- Proprietary and secret software is the moral equivalent of runners
-in a fist fight. Sad to say, the only referee we've got does not seem
-to object to fights; he just regulates them ("For every ten yards you
-run, you can fire one shot"). He really ought to break them up, and
-penalize runners for even trying to fight.
-
- "Won't everyone stop programming without a monetary incentive?"
-
- Actually, many people will program with absolutely no monetary
-incentive. Programming has an irresistible fascination for some
-people, usually the people who are best at it. There is no shortage of
-professional musicians who keep at it even though they have no hope of
-making a living that way.
-
- But really this question, though commonly asked, is not appropriate
-to the situation. Pay for programmers will not disappear, only become
-less. So the right question is, will anyone program with a reduced
-monetary incentive? My experience shows that they will.
-
- For more than ten years, many of the world's best programmers worked
-at the Artificial Intelligence Lab for far less money than they could
-have had anywhere else. They got many kinds of non-monetary rewards:
-fame and appreciation, for example. And creativity is also fun, a
-reward in itself.
-
- Then most of them left when offered a chance to do the same
-interesting work for a lot of money.
-
- What the facts show is that people will program for reasons other
-than riches; but if given a chance to make a lot of money as well, they
-will come to expect and demand it. Low-paying organizations do poorly
-in competition with high-paying ones, but they do not have to do badly
-if the high-paying ones are banned.
-
- "We need the programmers desperately. If they demand that we stop
- helping our neighbors, we have to obey."
-
- You're never so desperate that you have to obey this sort of demand.
-Remember: millions for defense, but not a cent for tribute!
-
- "Programmers need to make a living somehow."
-
- In the short run, this is true. However, there are plenty of ways
-that programmers could make a living without selling the right to use a
-program. This way is customary now because it brings programmers and
-businessmen the most money, not because it is the only way to make a
-living. It is easy to find other ways if you want to find them. Here
-are a number of examples.
-
- A manufacturer introducing a new computer will pay for the porting of
-operating systems onto the new hardware.
-
- The sale of teaching, hand-holding, and maintenance services could
-also employ programmers.
-
- People with new ideas could distribute programs as freeware and ask
-for donations from satisfied users or sell hand-holding services. I
-have met people who are already working this way successfully.
-
- Users with related needs can form users' groups and pay dues. A
-group would contract with programming companies to write programs that
-the group's members would like to use.
-
- All sorts of development can be funded with a Software Tax:
-
- Suppose everyone who buys a computer has to pay a certain percent
- of the price as a software tax. The government gives this to an
- agency like the NSF to spend on software development.
-
- But if the computer buyer makes a donation to software development
- himself, he can take a credit against the tax. He can donate to
- the project of his own choosing--often, chosen because he hopes to
- use the results when
-
- it is done. He can take a credit for any amount of donation up to
- the total tax he had to pay.
-
- The total tax rate could be decided by a vote of the payers of the
- tax, weighted according to the amount they will be taxed on.
-
- The consequences:
-
- * The computer-using community supports software development.
-
- * This community decides what level of support is needed.
-
- * Users who care which projects their share is spent on can
- choose this for themselves.

- In the long run, making programs free is a step toward the
-post-scarcity world, where nobody will have to work very hard just to
-make a living. People will be free to devote themselves to activities
-that are fun, such as programming, after spending the necessary ten
-hours a week on required tasks such as legislation, family counseling,
-robot repair, and asteroid prospecting. There will be no need to be
-able to make a living from programming.
+Face Resources
+--------------
- We have already greatly reduced the amount of work that the whole
-society must do for its actual productivity, but only a little of this
-has translated itself into leisure for workers because much
-nonproductive activity is required to accompany productive activity.
-The main causes of this are bureaucracy and isometric struggles against
-competition. Free software will greatly reduce these drains in the
-area of software production. We must do this, in order for technical
-gains in productivity to translate into less work for us.
+ The attributes of faces are also per-frame. They can be specified as:
+
+ Emacs.FACE_NAME.parameter: value
+
+or
+
+ Emacs*FRAME_NAME.FACE_NAME.parameter: value
+
+Faces accept the following resources:
+
+`attributeFont' (class `AttributeFont'): font-name
+ The font of this face.
+
+`attributeForeground' (class `AttributeForeground'): color-name
+`attributeBackground' (class `AttributeBackground'): color-name
+ The foreground and background colors of this face.
+
+`attributeBackgroundPixmap' (class `AttributeBackgroundPixmap'): file-name
+ The name of an XBM file (or XPM file, if your version of Emacs
+ supports XPM), to use as a background stipple.
+
+`attributeUnderline' (class `AttributeUnderline'): boolean
+ Whether text in this face should be underlined.
+
+ All text is displayed in some face, defaulting to the face named
+`default'. To set the font of normal text, use
+`Emacs*default.attributeFont'. To set it in the frame named `fred', use
+`Emacs*fred.default.attributeFont'.
+
+ These are the names of the predefined faces:
+
+`default'
+ Everything inherits from this.
+
+`bold'
+ If this is not specified in the resource database, Emacs tries to
+ find a bold version of the font of the default face.
+
+`italic'
+ If this is not specified in the resource database, Emacs tries to
+ find an italic version of the font of the default face.
+
+`bold-italic'
+ If this is not specified in the resource database, Emacs tries to
+ find a bold-italic version of the font of the default face.
+
+`modeline'
+ This is the face that the modeline is displayed in. If not
+ specified in the resource database, it is determined from the
+ default face by reversing the foreground and background colors.
+
+`highlight'
+ This is the face that highlighted extents (for example, Info
+ cross-references and possible completions, when the mouse passes
+ over them) are displayed in.
+
+`left-margin'
+`right-margin'
+ These are the faces that the left and right annotation margins are
+ displayed in.
+
+`zmacs-region'
+ This is the face that mouse selections are displayed in.
+
+`isearch'
+ This is the face that the matched text being searched for is
+ displayed in.
+
+`info-node'
+ This is the face of info menu items. If unspecified, it is copied
+ from `bold-italic'.
+
+`info-xref'
+ This is the face of info cross-references. If unspecified, it is
+ copied from `bold'. (Note that, when the mouse passes over a
+ cross-reference, the cross-reference's face is determined from a
+ combination of the `info-xref' and `highlight' faces.)
+
+ Other packages might define their own faces; to see a list of all
+faces, use any of the interactive face-manipulation commands such as
+`set-face-font' and type `?' when you are prompted for the name of a
+face.
+
+ If the `bold', `italic', and `bold-italic' faces are not specified
+in the resource database, then XEmacs attempts to derive them from the
+font of the default face. It can only succeed at this if you have
+specified the default font using the XLFD (X Logical Font Description)
+format, which looks like
+
+ *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
+
+If you use any of the other, less strict font name formats, some of
+which look like
+
+ lucidasanstypewriter-12
+ fixed
+ 9x13
+
+ then XEmacs won't be able to guess the names of the bold and italic
+versions. All X fonts can be referred to via XLFD-style names, so you
+should use those forms. See the man pages for `X(1)', `xlsfonts(1)',
+and `xfontsel(1)'.
+

+
+Widgets
+-------
+
+ There are several structural widgets between the terminal EmacsFrame
+widget and the top level ApplicationShell; the exact names and types of
+these widgets change from release to release (for example, they changed
+between 19.8 and 19.9, 19.9 and 19.10, and 19.10 and 19.12) and are
+subject to further change in the future, so you should avoid mentioning
+them in your resource database. The above-mentioned syntaxes should be
+forward- compatible. As of 19.13, the exact widget hierarchy is as
+follows:
+
+ INVOCATION-NAME "shell" "container" FRAME-NAME
+ x-emacs-application-class "EmacsShell" "EmacsManager" "EmacsFrame"
+
+ where INVOCATION-NAME is the terminal component of the name of the
+XEmacs executable (usually `xemacs'), and `x-emacs-application-class'
+is generally `Emacs'.
+
+\1f
+File: xemacs.info, Node: Menubar Resources, Prev: Widgets, Up: X Resources
+
+Menubar Resources
+-----------------
+
+ As the menubar is implemented as a widget which is not a part of
+XEmacs proper, it does not use the face mechanism for specifying fonts
+and colors: It uses whatever resources are appropriate to the type of
+widget which is used to implement it.
+
+ If Emacs was compiled to use only the Lucid Motif-lookalike menu
+widgets, then one way to specify the font of the menubar would be
+
+ Emacs*menubar*font: *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
+
+ If both the Lucid Motif-lookalike menu widgets and X Font Sets are
+configured to allow multilingual menubars, then one uses
+
+ *menubar*FontSet: -*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*, \
+ -*-*-*-*-*-*-*-120-*-jisx0208.1983-0
+
+ That would specify fonts for a Japanese menubar. Specifying only one
+XLFD is acceptable; specifying more than one for a given registry
+(language) is also allowed. When X Font Sets are configured, some .font
+resources (eg, menubars) are ignored in favor of the corresponding
+.fontSet resources.
+
+ If the Motif library is being used, then one would have to use
+
+ Emacs*menubar*fontList: *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
+
+ because the Motif library uses the `fontList' resource name instead
+of `font', which has subtly different semantics.
+
+ The same is true of the scrollbars: They accept whichever resources
+are appropriate for the toolkit in use.

+ Cancel an already-executed command, usually (`undo').
+
+ There are two ways of cancelling commands which are not finished
+executing: "quitting" with `C-g', and "aborting" with `C-]' or `M-x
+top-level'. Quitting is cancelling a partially typed command or one
+which is already running. Aborting is getting out of a recursive
+editing level and cancelling the command that invoked the recursive
+edit.
+
+ Quitting with `C-g' is used for getting rid of a partially typed
+command or a numeric argument that you don't want. It also stops a
+running command in the middle in a relatively safe way, so you can use
+it if you accidentally start executing a command that takes a long
+time. In particular, it is safe to quit out of killing; either your
+text will ALL still be there, or it will ALL be in the kill ring (or
+maybe both). Quitting an incremental search does special things
+documented under searching; in general, it may take two successive
+`C-g' characters to get out of a search. `C-g' works by setting the
+variable `quit-flag' to `t' the instant `C-g' is typed; Emacs Lisp
+checks this variable frequently and quits if it is non-`nil'. `C-g' is
+only actually executed as a command if it is typed while Emacs is
+waiting for input.
+
+ If you quit twice in a row before the first `C-g' is recognized, you
+activate the "emergency escape" feature and return to the shell. *Note
+Emergency Escape::.
+
+ You can use `C-]' (`abort-recursive-edit') to get out of a recursive
+editing level and cancel the command which invoked it. Quitting with
+`C-g' does not do this, and could not do this because it is used to
+cancel a partially typed command within the recursive editing level.
+Both operations are useful. For example, if you are in the Emacs
+debugger (*note Lisp Debug::) and have typed `C-u 8' to enter a numeric
+argument, you can cancel that argument with `C-g' and remain in the
+debugger.
+
+ The command `M-x top-level' is equivalent to "enough" `C-]' commands
+to get you out of all the levels of recursive edits that you are in.
+`C-]' only gets you out one level at a time, but `M-x top-level' goes
+out all levels at once. Both `C-]' and `M-x top-level' are like all
+other commands and unlike `C-g' in that they are effective only when
+Emacs is ready for a command. `C-]' is an ordinary key and has its
+meaning only because of its binding in the keymap. *Note Recursive
+Edit::.
+
+ `C-x u' (`undo') is not strictly speaking a way of cancelling a
+command, but you can think of it as cancelling a command already
+finished executing. *Note Undo::.

+Recursive Editing Levels
+------------------------
+
+ Recursive editing levels are important and useful features of Emacs,
+but they can seem like malfunctions to the user who does not understand
+them.
+
+ If the mode line has square brackets `[...]' around the parentheses
+that contain the names of the major and minor modes, you have entered a
+recursive editing level. If you did not do this on purpose, or if you
+don't understand what that means, you should just get out of the
+recursive editing level. To do so, type `M-x top-level'. This is
+called getting back to top level. *Note Recursive Edit::.
+
+\1f
+File: xemacs.info, Node: Screen Garbled, Next: Text Garbled, Prev: Stuck Recursive, Up: Lossage
+
+Garbage on the Screen
+---------------------
+
+ If the data on the screen looks wrong, the first thing to do is see
+whether the text is actually wrong. Type `C-l', to redisplay the
+entire screen. If the text appears correct after this, the problem was
+entirely in the previous screen update.
+
+ Display updating problems often result from an incorrect termcap
+entry for the terminal you are using. The file `etc/TERMS' in the Emacs
+distribution gives the fixes for known problems of this sort.
+`INSTALL' contains general advice for these problems in one of its
+sections. Very likely there is simply insufficient padding for certain
+display operations. To investigate the possibility that you have this
+sort of problem, try Emacs on another terminal made by a different
+manufacturer. If problems happen frequently on one kind of terminal but
+not another kind, the real problem is likely to be a bad termcap entry,
+though it could also be due to a bug in Emacs that appears for terminals
+that have or lack specific features.
+

+
+Garbage in the Text
+-------------------
+
+ If `C-l' shows that the text is wrong, try undoing the changes to it
+using `C-x u' until it gets back to a state you consider correct. Also
+try `C-h l' to find out what command you typed to produce the observed
+results.
+
+ If a large portion of text appears to be missing at the beginning or
+end of the buffer, check for the word `Narrow' in the mode line. If it
+appears, the text is still present, but marked off-limits. To make it
+visible again, type `C-x n w'. *Note Narrowing::.
+

+File: xemacs.info, Node: Unasked-for Search, Next: Emergency Escape, Prev: Text Garbled, Up: Lossage
+
+Spontaneous Entry to Incremental Search
+---------------------------------------
+
+ If Emacs spontaneously displays `I-search:' at the bottom of the
+screen, it means that the terminal is sending `C-s' and `C-q' according
+to the poorly designed xon/xoff "flow control" protocol. You should
+try to prevent this by putting the terminal in a mode where it will not
+use flow control, or by giving it enough padding that it will never
+send a `C-s'. If that cannot be done, you must tell Emacs to expect
+flow control to be used, until you can get a properly designed terminal.
+
+ Information on how to do these things can be found in the file
+`INSTALL' in the Emacs distribution.
+
+\1f
+File: xemacs.info, Node: Emergency Escape, Next: Total Frustration, Prev: Unasked-for Search, Up: Lossage
+
+Emergency Escape
+----------------
+
+ Because at times there have been bugs causing Emacs to loop without
+checking `quit-flag', a special feature causes Emacs to be suspended
+immediately if you type a second `C-g' while the flag is already set,
+so you can always get out of XEmacs. Normally Emacs recognizes and
+clears `quit-flag' (and quits!) quickly enough to prevent this from
+happening.
+
+ When you resume Emacs after a suspension caused by multiple `C-g', it
+asks two questions before going back to what it had been doing:
+
+ Auto-save? (y or n)
+ Abort (and dump core)? (y or n)
+
+Answer each one with `y' or `n' followed by <RET>.
+
+ Saying `y' to `Auto-save?' causes immediate auto-saving of all
+modified buffers in which auto-saving is enabled.
+
+ Saying `y' to `Abort (and dump core)?' causes an illegal instruction
+to be executed, dumping core. This is to enable a wizard to figure out
+why Emacs was failing to quit in the first place. Execution does not
+continue after a core dump. If you answer `n', execution does
+continue. With luck, Emacs will ultimately check `quit-flag' and quit
+normally. If not, and you type another `C-g', it is suspended again.
+
+ If Emacs is not really hung, but is just being slow, you may invoke
+the double `C-g' feature without really meaning to. In that case,
+simply resume and answer `n' to both questions, and you will arrive at
+your former state. Presumably the quit you requested will happen soon.
+
+ The double-`C-g' feature may be turned off when Emacs is running
+under a window system, since the window system always enables you to
+kill Emacs or to create another window and run another program.

+
+Help for Total Frustration
+--------------------------
+
+ If using Emacs (or something else) becomes terribly frustrating and
+none of the techniques described above solve the problem, Emacs can
+still help you.
+
+ First, if the Emacs you are using is not responding to commands, type
+`C-g C-g' to get out of it and then start a new one.
+
+ Second, type `M-x doctor <RET>'.
+
+ The doctor will make you feel better. Each time you say something to
+the doctor, you must end it by typing <RET> <RET>. This lets the
+doctor know you are finished.

+Reporting Bugs
+==============
+
+ Sometimes you will encounter a bug in Emacs. Although we cannot
+promise we can or will fix the bug, and we might not even agree that it
+is a bug, we want to hear about bugs you encounter in case we do want
+to fix them.
+
+ To make it possible for us to fix a bug, you must report it. In
+order to do so effectively, you must know when and how to do it.
+
+When Is There a Bug
+-------------------
+
+ If Emacs executes an illegal instruction, or dies with an operating
+system error message that indicates a problem in the program (as
+opposed to something like "disk full"), then it is certainly a bug.
+
+ If Emacs updates the display in a way that does not correspond to
+what is in the buffer, then it is certainly a bug. If a command seems
+to do the wrong thing but the problem corrects itself if you type
+`C-l', it is a case of incorrect display updating.
+
+ Taking forever to complete a command can be a bug, but you must make
+certain that it was really Emacs's fault. Some commands simply take a
+long time. Type `C-g' and then `C-h l' to see whether the input Emacs
+received was what you intended to type; if the input was such that you
+KNOW it should have been processed quickly, report a bug. If you don't
+know whether the command should take a long time, find out by looking
+in the manual or by asking for assistance.
+
+ If a command you are familiar with causes an Emacs error message in a
+case where its usual definition ought to be reasonable, it is probably a
+bug.
+
+ If a command does the wrong thing, that is a bug. But be sure you
+know for certain what it ought to have done. If you aren't familiar
+with the command, or don't know for certain how the command is supposed
+to work, then it might actually be working right. Rather than jumping
+to conclusions, show the problem to someone who knows for certain.
+
+ Finally, a command's intended definition may not be best for editing
+with. This is a very important sort of problem, but it is also a
+matter of judgment. Also, it is easy to come to such a conclusion out
+of ignorance of some of the existing features. It is probably best not
+to complain about such a problem until you have checked the
+documentation in the usual ways, feel confident that you understand it,
+and know for certain that what you want is not available. If you are
+not sure what the command is supposed to do after a careful reading of
+the manual, check the index and glossary for any terms that may be
+unclear. If you still do not understand, this indicates a bug in the
+manual. The manual's job is to make everything clear. It is just as
+important to report documentation bugs as program bugs.
+
+ If the online documentation string of a function or variable
+disagrees with the manual, one of them must be wrong, so report the bug.
+
+How to Report a Bug
+-------------------
+
+ When you decide that there is a bug, it is important to report it
+and to report it in a way which is useful. What is most useful is an
+exact description of what commands you type, starting with the shell
+command to run Emacs, until the problem happens. Always include the
+version number of Emacs that you are using; type `M-x emacs-version' to
+print this.
+
+ The most important principle in reporting a bug is to report FACTS,
+not hypotheses or categorizations. It is always easier to report the
+facts, but people seem to prefer to strain to posit explanations and
+report them instead. If the explanations are based on guesses about
+how Emacs is implemented, they will be useless; we will have to try to
+figure out what the facts must have been to lead to such speculations.
+Sometimes this is impossible. But in any case, it is unnecessary work
+for us.
+
+ For example, suppose that you type `C-x C-f /glorp/baz.ugh <RET>',
+visiting a file which (you know) happens to be rather large, and Emacs
+prints out `I feel pretty today'. The best way to report the bug is
+with a sentence like the preceding one, because it gives all the facts
+and nothing but the facts.
+
+ Do not assume that the problem is due to the size of the file and
+say, "When I visit a large file, Emacs prints out `I feel pretty
+today'." This is what we mean by "guessing explanations". The problem
+is just as likely to be due to the fact that there is a `z' in the file
+name. If this is so, then when we got your report, we would try out
+the problem with some "large file", probably with no `z' in its name,
+and not find anything wrong. There is no way in the world that we
+could guess that we should try visiting a file with a `z' in its name.
+
+ Alternatively, the problem might be due to the fact that the file
+starts with exactly 25 spaces. For this reason, you should make sure
+that you inform us of the exact contents of any file that is needed to
+reproduce the bug. What if the problem only occurs when you have typed
+the `C-x a l' command previously? This is why we ask you to give the
+exact sequence of characters you typed since starting to use Emacs.
+
+ You should not even say "visit a file" instead of `C-x C-f' unless
+you know that it makes no difference which visiting command is used.
+Similarly, rather than saying "if I have three characters on the line,"
+say "after I type `<RET> A B C <RET> C-p'," if that is the way you
+entered the text.
+
+ If you are not in Fundamental mode when the problem occurs, you
+should say what mode you are in.
+
+ If the manifestation of the bug is an Emacs error message, it is
+important to report not just the text of the error message but a
+backtrace showing how the Lisp program in Emacs arrived at the error.
+To make the backtrace, you must execute the Lisp expression `(setq
+debug-on-error t)' before the error happens (that is to say, you must
+execute that expression and then make the bug happen). This causes the
+Lisp debugger to run (*note Lisp Debug::). The debugger's backtrace
+can be copied as text into the bug report. This use of the debugger is
+possible only if you know how to make the bug happen again. Do note
+the error message the first time the bug happens, so if you can't make
+it happen again, you can report at least that.
+
+ Check whether any programs you have loaded into the Lisp world,
+including your init file, set any variables that may affect the
+functioning of Emacs. *Note Init File::. Also, see whether the
+problem happens in a freshly started Emacs without loading your init
+file (start Emacs with the `-q' switch to prevent loading the init
+file). If the problem does NOT occur then, it is essential that we
+know the contents of any programs that you must load into the Lisp
+world in order to cause the problem to occur.
+
+ If the problem does depend on an init file or other Lisp programs
+that are not part of the standard Emacs system, then you should make
+sure it is not a bug in those programs by complaining to their
+maintainers first. After they verify that they are using Emacs in a
+way that is supposed to work, they should report the bug.
+
+ If you can tell us a way to cause the problem without visiting any
+files, please do so. This makes it much easier to debug. If you do
+need files, make sure you arrange for us to see their exact contents.
+For example, it can often matter whether there are spaces at the ends
+of lines, or a newline after the last line in the buffer (nothing ought
+to care whether the last line is terminated, but tell that to the bugs).
+
+ The easy way to record the input to Emacs precisely is to write a
+dribble file; execute the Lisp expression:
+
+ (open-dribble-file "~/dribble")
+
+using `Meta-<ESC>' or from the `*scratch*' buffer just after starting
+Emacs. From then on, all Emacs input will be written in the specified
+dribble file until the Emacs process is killed.
+
+ For possible display bugs, it is important to report the terminal
+type (the value of environment variable `TERM'), the complete termcap
+entry for the terminal from `/etc/termcap' (since that file is not
+identical on all machines), and the output that Emacs actually sent to
+the terminal. The way to collect this output is to execute the Lisp
+expression:
+
+ (open-termscript "~/termscript")
+
+using `Meta-<ESC>' or from the `*scratch*' buffer just after starting
+Emacs. From then on, all output from Emacs to the terminal will be
+written in the specified termscript file as well, until the Emacs
+process is killed. If the problem happens when Emacs starts up, put
+this expression into your init file so that the termscript file will be
+open when Emacs displays the screen for the first time. *Note Init
+File::. Be warned: it is often difficult, and sometimes impossible, to
+fix a terminal-dependent bug without access to a terminal of the type
+that stimulates the bug.
