-@node Overview
-@chapter Overview
-
-The Modus themes are designed for accessible readability. They conform
-with the highest standard for color contrast between any given
-combination of background and foreground values. This corresponds to
-the WCAG AAA standard, which specifies a minimum rate of distance in
-relative luminance of 7:1.
-
-Modus Operandi (@samp{modus-operandi}) is a light theme, while Modus Vivendi
-(@samp{modus-vivendi}) is dark. Each theme's color palette is designed to
-meet the needs of the numerous interfaces that are possible in the Emacs
-computing environment.
-
-The overarching objective of this project is to always offer accessible
-color combinations. There shall never be a compromise on this
-principle. If there arises an inescapable trade-off between readability
-and stylistic considerations, we will always opt for the former.
-
-To ensure that users have a consistently accessible experience, the
-themes strive to achieve as close to full face coverage as possible
-(see @ref{Face coverage}).
-
-Starting with version 0.12.0 and onwards, the themes are built into GNU
-Emacs (current version is 0.13.0).

-@node Installation
-@chapter Installation
-
-The Modus themes are distributed with Emacs starting with version 28.1.
-On older versions of Emacs, they can be installed using Emacs' package
-manager or manually from their code repository.
-
-Modus Operandi (light theme) and Modus Vivendi (dark) are normally
-distributed as standalone packages in Emacs-specific archives. There
-also exist packages for GNU/Linux distributions.
-

-@end menu
-
-@node Install from the archives
-@section Install from the archives
-
-@samp{modus-operandi-theme} and @samp{modus-vivendi-theme} are
-available from the GNU ELPA archive, which is configured by default.
-
-Prior to querying any package archive, make sure to have updated the
-index, with @samp{M-x package-refresh-contents}. Then all you need to do is
-type @samp{M-x package-install} and specify the theme of your choice.
-
-@node Install on GNU/Linux
-@section Install on GNU/Linux
-
-The themes are also available from the archives of some GNU/Linux
-distributions. These should correspond to a tagged release rather than
-building directly from the latest Git commit. It all depends on the
-distro's packaging policies.

-
-@node Debian 11 Bullseye
-@subsection Debian 11 Bullseye
-
-The two themes are distributed as a single package for Debian and its
-derivatives. Currently in the unstable and testing suites and should be
-available in time for Debian 11 Bullseye (next stable).
-
-Get them with:
-
-@example
-sudo apt install elpa-modus-themes
-@end example
-
-@node GNU Guix
-@subsection GNU Guix
-
-Users of either the Guix System (the distro) or just Guix (the package
-manager) can get each theme as a standalone package.

-@chapter Enable and load
-
-This section documents how to load the theme of your choice and how to
-further control its initialization. It also includes some sample code
-snippets that could help you in the task, especially if you intend to
-use both Modus Operandi and Modus Vivendi.

-@node Load automatically
-@section Load automatically
-
-A simple way to load the theme from your Emacs initialization file is to
-include either of the following expressions:
-
-@lisp
-(load-theme 'modus-operandi t) ; Light theme
-(load-theme 'modus-vivendi t) ; Dark theme
-@end lisp
-
-Make sure to remove any other theme that is being loaded, otherwise you
-might run into unexpected issues.
-
-Note that you can always @samp{M-x disable-theme} and specify an item. The
-command does exactly what its name suggests. To deactivate all enabled
-themes at once, in case you have multiple of them enabled, you may
-evaluate the expression:
-
-@lisp
-(mapc #'disable-theme custom-enabled-themes)
-@end lisp
-
-@node Load at a given time or at sunset/sunrise
-@section Load at a given time or at sunset/sunrise
-
-It is possible to schedule a time during the day at or after which a
-given theme will be loaded.@footnote{Contributed on Reddit by user @samp{b3n}
-@uref{https://www.reddit.com/r/emacs/comments/gdtqov/weekly_tipstricketc_thread/fq9186h/}.}
-
-@lisp
-;; Light for the day
-(load-theme 'modus-operandi t t)
-(run-at-time "05:00" (* 60 60 24)
- (lambda ()
- (enable-theme 'modus-operandi)))
-
-;; Dark for the night
-(load-theme 'modus-vivendi t t)
-(run-at-time "21:00" (* 60 60 24)
- (lambda ()
- (enable-theme 'modus-vivendi)))
-@end lisp
-
-A modified version of the above technique is to use the sunrise and
-sunset as references, instead of specifying a fixed hour value.@footnote{Contributed directly by André Alexandre Gomes @uref{https://gitlab.com/aadcg}.}
-If you set @samp{calendar-latitude} and @samp{calendar-longitude} (defined in the
-built-in @samp{solar.el} library---read it with @samp{M-x find-library}), you can
-automatically switch between both themes at the appropriate time-of-day.
-Note that @emph{those calendar variables need to be set before loading the
-themes}.
-
-@lisp
-;; Define coordinates
-(setq calendar-latitude 35.17
- calendar-longitude 33.36)
-
-;; Light at sunrise
-(load-theme 'modus-operandi t t)
-(run-at-time (nth 1 (split-string (sunrise-sunset)))

- (* 60 60 24)
- (lambda ()
- (enable-theme 'modus-vivendi)))
-@end lisp
-
-For the sake of completeness, the @samp{load-theme} call in these snippets is
-slightly different than the one shown in @ref{Load automatically}, because it
-does not enable the theme directly: the subsequent @samp{enable-theme} does
-that when needed.
-
-@node Toggle between the themes on demand
-@section Toggle between the themes on demand
-
-With both themes available, it is possible to design a simple command to
-switch between them on demand.
-

- "Toggle between `modus-operandi' and `modus-vivendi' themes."

- (if (eq (car custom-enabled-themes) 'modus-operandi)
- (progn
- (disable-theme 'modus-operandi)
- (load-theme 'modus-vivendi t))
- (disable-theme 'modus-vivendi)
- (load-theme 'modus-operandi t)))
-@end lisp
-
-You could use @samp{(mapc #'disable-theme custom-enabled-themes)} instead of
-disabling a single target, but you get the idea.
-
-@node Configure options prior to loading
-@section Configure options prior to loading
-
-If you plan to use both themes and wish to apply styles consistently
-(see @ref{Customization Options}), you could define wrapper functions around
-the standard @samp{load-theme} command. These extend the simple function we
-presented in @ref{Toggle between the themes on demand}.

-This is to ensure that those constructs remain monospaced when users opt
-for something like the built-in @kbd{M-x variable-pitch-mode}. Otherwise the
-layout would appear broken. To disable this behaviour, set the option
-to @samp{t}.
-
-Users may prefer to use another package for handling mixed typeface

-@item
-@samp{nil} (default)
-@item
-@samp{3d}
-@item
-@samp{moody}
-@end enumerate
-
-The default value (@samp{nil}) produces a two-dimensional effect both for the
-active and inactive modelines. The differences between the two are
-limited to distinct shades of greyscale values, with the active being
-more intense than the inactive.
-
-A @samp{3d} symbol will make the active modeline look like a three-dimensional
-rectangle. Inactive modelines remain 2D, though they are slightly toned
-down relative to the default. This aesthetic is the same as what you
-get when you run Emacs without any customizations (@kbd{emacs -Q} on the
-command line).
-
-While @samp{moody} removes all box effects from the modelines and applies
-underline and overline properties instead. It also tones down a bit the
-inactive modelines. This is meant to optimize things for use with the
-@uref{https://github.com/tarsius/moody, moody package} (hereinafter referred to as ``Moody''), though it can work
-fine even without it.
-
-Note that Moody does not expose any faces that the themes could style
-directly. Instead it re-purposes existing ones to render its tabs and
-ribbons. As such, there may be cases where the contrast ratio falls
-below the 7:1 target that the themes conform with (WCAG AAA). To hedge
-against this, we configure a fallback foreground for the @samp{moody} option,
-which will come into effect when the background of the modeline changes
-to something less accessible, such as Moody ribbons (read the doc string
-of @samp{set-face-attribute}, specifically @samp{:distant-foreground}). This fallback
-comes into effect when Emacs determines that the background and
-foreground of the given construct are too close to each other in terms
-of color distance. In effect, users would need to experiment with the
-variable @samp{face-near-same-color-threshold} to trigger the fallback color.
-We find that a value of @samp{45000} would suffice, contrary to the default
-@samp{30000}. Do not set the value too high, because that would have the
-adverse effect of always overriding the default color (which has been
-carefully designed to be highly accessible).
-
-Furthermore, because Moody expects an underline and overline instead of
-a box style, it is recommended you also include this in your setup:

-@item
-@samp{opinionated}

-
-This is a special option that has different effects depending on the
-completion UI@. The interfaces can be grouped in two categories, based
-on their default aesthetics: (i) those that only or mostly use
-foreground colors for their interaction model, and (ii) those that
-combine background and foreground values for some of their metaphors.
-The former category encompasses Icomplete, Ido, Selectrum as well as
-pattern matching styles like Orderless and Flx. The latter covers Helm,
-Ivy, and similar.
-
-A value of @samp{nil} will respect the metaphors of each completion framework.
-
-The symbol @samp{moderate} will apply a combination of background and
-foreground that is fairly subtle. For Icomplete and friends this
-constitutes a departure from their default aesthetics, however the
-difference is small. While Helm et al will appear slightly different
-than their original looks, as they are toned down a bit.
-
-The symbol @samp{opinionated} will apply color combinations that refashion the
-completion UI@. For the Icomplete camp this means that intense
-background and foreground combinations are used: in effect their looks
-emulate those of Ivy and co. in their original style. Whereas the other
-group of packages will revert to an even more nuanced aesthetic with
-some additional changes to the choice of hues.
-
-To appreciate the scope of this customization option, you should spend
-some time with every one of the @samp{nil} (default), @samp{moderate}, and @samp{opinionated}
-possibilities.

-
-The ``subtle'' symbol will apply a greyscale background that is visible,

-@enumerate
-@item
-@samp{nil} (default)
-@item
-@samp{desaturated}
-@item
-@samp{fg-only}
-@end enumerate
-
-By default the themes will apply richly colored backgrounds to the
-output of diffs, such as those of @samp{diff-mode}, @samp{ediff}, @samp{smerge-mode}, and
-@samp{magit}. These are color combinations of an accented background and
-foreground so that, for example, added lines have a pronounced green
-background with an appropriate shade of green for the affected text.
-Word-wise or ``refined'' changes follow this pattern but use different
-shades of those colors to remain distinct.
-
-A @samp{desaturated} value tones down all relevant color values. It still
-combines an accented background with an appropriate foreground, yet its
-overall impression is very subtle. Refined changes are a bit more
-intense to fulfil their intended function, though still less saturated
-than default.
-
-While @samp{fg-only} will remove all accented backgrounds and instead rely on
-color-coded text to denote changes. For instance, added lines use an
-intense green foreground, while their background is the same as the rest
-of the buffer. Word-wise highlights still use a background value which
-is, nonetheless, more subtle than its default equivalent.
-
-Concerning @samp{magit}, an extra set of tweaks are introduced for the effect
-of highlighting the current diff hunk, so as to remain consistent with
-the overall experience of that mode. Expect changes that are consistent
-with the overall intent of the aforementioned.

-@item
-@samp{rainbow}
-@end enumerate
-
-The default is to use the same background as the rest of the buffer for
-the contents of the block.
-
-A value of @samp{greyscale} will apply a subtle neutral gray background to the
-block's contents. It will also extend to the edge of the window the
-background of the ``begin'' and ``end'' block delimiter lines (only relevant
-for Emacs versions >= 27 where the 'extend' keyword is recognised by
-@samp{set-face-attribute}).
-
-While @samp{rainbow} will instead use an accented background for the contents
-of the block. The exact color will depend on the programming language
-and is controlled by the @samp{org-src-block-faces} variable (refer to the
-theme's source code for the current association list). This is most
-suitable for users who work on literate programming documents that mix
-and match several languages.
-
-Note that the ``rainbow'' blocks may require you to also reload the
-major-mode so that the colors are applied properly: use @kbd{M-x org-mode} or
-@kbd{M-x org-mode-restart} to refresh the buffer. Or start typing in each
-code block (inefficient at scale, but it still works).

-(setq modus-operandi-theme-headings
- '((1 . section)
- (2 . line)
- (3 . highlight)
- (t . rainbow-no-bold)))
-@end lisp
-
-The above uses the @samp{section} value for heading levels 1, the @samp{line} for
-headings 2, @samp{highlight} for 3. All other levels fall back to
-@samp{rainbow-line-no-bold}.
-
-To set a uniform value for all heading levels, use this pattern:
-
-@lisp
-;; A given style for every heading
-(setq modus-operandi-theme-headings
- '((t . rainbow-line-no-bold)))
-
-;; Default aesthetic for every heading
-(setq modus-operandi-theme-headings
- '((t . nil)))
-@end lisp
-
-The default style for headings uses a fairly desaturated foreground
-value in combination with a bold typographic weight. To specify this
-style for a given level N (assuming you wish to have another fallback
-option), just specify the value @samp{t} like this:
-
-@lisp
-(setq modus-operandi-theme-headings
- '((1 . t)

-
-@item
-If it is an integer, it is read as an absolute font height. The
-number is basically the point size multiplied by ten. So if you want
-it to be @samp{18pt} you must pass @samp{180}. Please understand that setting an
-absolute value is discouraged, as it will break the layout when you
-try to change font sizes with the built-in @samp{text-scale-adjust} command
-(see @ref{Font configs (DIY), , Font configurations}).
-@end itemize
-
-Below are the variables in their default values, using the floating

-@lisp
-(setq modus-operandi-theme-scale-1 1.05

-
-The themes are designed to cope well with mixed font settings (@ref{No mixed fonts, , Option
-for no font mixing}). Currently this applies to @samp{org-mode} and
-@samp{markdown-mode}.
-
-In practice it means that the user can safely opt for a more
-prose-friendly proportionately spaced typeface as their default, while
-letting spacing-sensitive elements like tables and inline code always
-use a monospaced font, by inheriting from the @samp{fixed-pitch} face.
-
-Users can try the built-in @kbd{M-x variable-pitch-mode} to see the effect in
-action.
-
-To make everything use your desired font families, you need to configure
-the @samp{variable-pitch} (proportional spacing) and @samp{fixed-pitch} (monospaced)
-faces respectively. It may also be convenient to set your main typeface
-by configuring the @samp{default} face the same way.
-
-Put something like this in your initialization file (make sure to read
-the documentation of @samp{set-face-attribute}, with @kbd{M-x describe-function}):
-
-@lisp
-;; Main typeface
-(set-face-attribute 'default nil :family "DejaVu Sans Mono" :height 110)
-
-;; Proportionately spaced typeface
-(set-face-attribute 'variable-pitch nil :family "DejaVu Serif" :height 1.0)
-
-;; Monospaced typeface
-(set-face-attribute 'fixed-pitch nil :family "DejaVu Sans Mono" :height 1.0)
-@end lisp
-
-Note the differences in the @samp{:height} property. The @samp{default} face must
-specify an absolute value, which is the point size × 10. So if you want
-to use a font at point size @samp{11}, you set the height at @samp{110}.@footnote{@samp{:height}
-values do not need to be rounded to multiples of ten: the likes of @samp{115}
-are perfectly valid—some typefaces will change to account for those
-finer increments.} Whereas every other face must have a value that is
-relative to the default, represented as a floating point (if you use an
-integer, say, @samp{15} then that means an absolute height). This is of
-paramount importantance: it ensures that all fonts can scale gracefully
-when using something like the @samp{text-scale-adjust} command which only
-operates on the base font size (i.e. the @samp{default} face's absolute
-height).
-
-An alternative syntax for the @samp{default} face, is to pass all typeface
-parameters directly to a @samp{font} property.@footnote{Has the benefit of
-accepting @samp{fontconfig} parameters (GNU/Linux), such as @samp{"DejaVu Sans
-Mono-11:hintstyle=hintslight:autohint=false"}.
-@uref{https://www.freedesktop.org/software/fontconfig/fontconfig-user.html}}
-Note that here we use a standard point size:
-
-@lisp
-(set-face-attribute 'default nil :font "DejaVu Sans Mono-11")
-@end lisp
-
-Again, remember to only ever specify an absolute height for the @samp{default}.

-@node Org user faces (DIY)
-@section Org user faces (DIY)
-
-Users of @samp{org-mode} have the option to configure various keywords and
-priority cookies to better match their workflow. User options are
-@samp{org-todo-keyword-faces} and @samp{org-priority-faces}.
-
-As those are meant to be custom faces, it would be futile to have the
-themes try to guess what each user would want to use, which keywords to
-target, and so on. Instead, we can provide guidelines on how to
-customize things to one's liking with the intent of retaining the
-overall aesthetics of the theme.
-
-Please bear in mind that the end result of those is not controlled by
-the active theme but by how Org maps faces to its constructs. Editing
-those while @samp{org-mode} is active requires @kbd{M-x org-mode-restart} for changes
-to take effect.
-
-Let us assume you wish to visually differentiate your keywords. You
-have something like this:
-
-@lisp
-(setq org-todo-keywords
- '((sequence "TODO(t)" "|" "DONE(D)" "CANCEL(C)")
- (sequence "MEET(m)" "|" "MET(M)")
- (sequence "STUDY(s)" "|" "STUDIED(S)")
- (sequence "WRITE(w)" "|" "WROTE(W)")))
-@end lisp
-
-You could then use a variant of the following to inherit from a face
-that uses the styles you want and also to preserve the properties
-applied by the @samp{org-todo} face:
-
-@lisp
-(setq org-todo-keyword-faces
- '(("MEET" . '(font-lock-preprocessor-face org-todo))
- ("STUDY" . '(font-lock-variable-name-face org-todo))
- ("WRITE" . '(font-lock-type-face org-todo))))
-@end lisp
-
-This will refashion the keywords you specify, while letting the other
-items in @samp{org-todo-keywords} use their original styles (which are defined
-in the @samp{org-todo} and @samp{org-done} faces).
-
-If you want back the defaults, try specifying just the @samp{org-todo} face:
-
-@lisp
-(setq org-todo-keyword-faces
- '(("MEET" . org-todo)
- ("STUDY" . org-todo)
- ("WRITE" . org-todo)))
-@end lisp
-
-When you inherit from multiple faces, you need to quote the list as
-shown further above. The order is important: the last item is applied
-over the previous ones. If you do not want to blend multiple faces, you
-do not need a quoted list. A pattern of @samp{keyword . face} would suffice.
-
-Both approaches can be used simultaneously, as illustrated in this
-configuration of the priority cookies:
-
-@lisp
-(setq org-priority-faces
- '((?A . '(org-scheduled-today org-priority))
- (?B . org-priority)
- (?C . '(shadow org-priority))))
-@end lisp
-
-To find all the faces that are loaded in your current Emacs session, use
-@kbd{M-x list-faces-display}. Also try @kbd{M-x describe-variable} and then specify
-the name of each of those Org variables demonstrated above. Their
-documentation strings will offer you further guidance.
-
-Furthermore, consider reading the ``Notes for aspiring Emacs theme
-developers'', published on 2020-08-28 by me (Protesilaos Stavrou):

-@node Will NOT be supported
-@section Will NOT be supported
-
-I have thus far identified a single package that does fit into the
-overarching objective of this project: @uref{https://github.com/hlissner/emacs-solaire-mode, solaire}. It basically tries to
-cast a less intense background on the main file-visiting buffers, so
-that secondary elements like sidebars can have the default (pure
-white/black) background.
-
-I will only cover this package if it ever supports the inverse effect:
-less intense colors (but still accessible) for ancillary interfaces
-and the intended styles for the content you are actually working on.

-
-@node Note on company-mode overlay pop-up
-@section Note on company-mode overlay pop-up
-
-By default, the @samp{company-mode} pop-up that lists completion candidates is
-drawn using an overlay. This creates alignment issues every time it is
-placed above a piece of text that has a different height than the
-default.
-
-The solution recommended by the project's maintainer is to use an
-alternative front-end for drawing the pop-up which uses child frames
-instead of overlays.@footnote{@uref{https://github.com/company-mode/company-mode/issues/1010}}@footnote{@uref{https://github.com/tumashu/company-posframe/}}
-
-@node Note for ERC escaped color sequences
-@section Note for ERC escaped color sequences
-
-The built-in IRC client @samp{erc} has the ability to colorise any text using
-escape sequences that start with @samp{^C} (inserted with @samp{C-q C-c}) and are
-followed by a number for the foreground and background.@footnote{This page
-explains the basics, though it is not specific to Emacs:
-@uref{https://www.mirc.com/colors.html}} Possible numbers are 0-15, with the
-first entry being the foreground and the second the background,
-separated by a comma. Like this @samp{^C1,6}. The minimum setup is this:
-
-@lisp
-(add-to-list 'erc-modules 'irccontrols)
-(setq erc-interpret-controls-p t
- erc-interpret-mirc-color t)
-@end lisp
-
-As this allows users to make arbitrary combinations, it is impossible to
-guarantee a consistently high contrast ratio. All we can we do is
-provide guidance on the combinations that satisfy the accessibility
-standard of the themes:
-
-@table @asis
-@item Modus Operandi
-Use foreground color 1 for all backgrounds from
-2-15. Like so: @samp{C-q C-c1,N} where @samp{N} is the background.
-
-@item Modus Vivendi
-Use foreground color 0 for all backgrounds from
-2-13. Use foreground @samp{1} for backgrounds 14, 15.
-@end table
-
-Colors 0 and 1 are white and black respectively. So combine them
-together, if you must.
-
-@node Note for powerline or spaceline
-@section Note for powerline or spaceline
-
-Both Powerline and Spaceline package users will likely need to use the
-command @samp{powerline-reset} whenever they make changes to their themes
-and/or modeline setup.
-
-@node Note on shr colors
-@section Note on shr colors
-
-Emacs' HTML rendering mechanism (@samp{shr}) may need explicit configuration to
-respect the theme's colors instead of whatever specifications the
-webpage provides. Consult @kbd{C-h v shr-use-colors}.
-
-@node Note for Helm grep
-@section Note for Helm grep
-
-There is one face from the Helm package that is meant to highlight the
-matches of a grep or grep-like command (@samp{ag} or @samp{ripgrep}). It is
-@samp{helm-grep-match}. However, this face can only apply when the user does
-not pass @samp{--color=always} as a command-line option for their command.
-
-Here is the docstring for that face, which is defined in the
-@samp{helm-grep.el} library (view a library with @samp{M-x find-library}).
-
-@quotation
-Face used to highlight grep matches. Have no effect when grep backend
-use ``--color=''
-
-@end quotation
-
-The user must either remove @samp{--color} from the flags passed to the grep
-function, or explicitly use @samp{--color=never} (or equivalent). Helm
-provides user-facing customization options for controlling the grep
-function's parameters, such as @samp{helm-grep-default-command} and
-@samp{helm-grep-git-grep-command}.
-
-When @samp{--color=always} is in effect, the grep output will use red text in
-bold letter forms to present the matching part in the list of
-candidates. That style still meets the contrast ratio target of >= 7:1
-(accessibility standard WCAG AAA), because it draws the reference to
-ANSI color number 1 (red) from the already-supported array of
-@samp{ansi-color-names-vector}.
-
-@node Note on vc-annotate-background-mode
-@section Note on vc-annotate-background-mode
-
-Due to the unique way @samp{vc-annotate} (@kbd{C-x v g}) applies colors, support for
-its background mode (@samp{vc-annotate-background-mode}) is disabled at the
-theme level.
-
-Normally, such a drastic measure should not belong in a theme: assuming
-the user's preferences is bad practice. However, it has been deemed
-necessary in the interest of preserving color contrast accessibility
-while still supporting a useful built-in tool.
-
-If there actually is a way to avoid such a course of action, without
-prejudice to the accessibility standard of this project, then please
-report as much or send patches (see @ref{Contributing}).

-
-The @samp{modus-operandi} and @samp{modus-vivendi} themes are built into Emacs.
-Currently they are in the project's @samp{master} branch, which is tracking the
-next development release target.
-
-The source code of the themes is @uref{https://gitlab.com/protesilaos/modus-themes/, available on Gitlab}, for the time
-being. A @uref{https://github.com/protesilaos/modus-themes/, mirror on Github} is also on offer.

-
-It would be great if your feedback also includes some screenshots, GIFs,
-or short videos, as well as further instructions to reproduce a given
-setup. Though this is not a requirement.
-
-Whatever you do, bear in mind the overarching objective of the Modus
-themes: to keep a contrast ratio that is greater or equal to 7:1 between
-background and foreground colors. If a compromise is ever necessary
-between aesthetics and accessibility, it shall always be made in the
-interest of the latter.
-
-@node Merge requests
-@section Patches require copyright assignment to the FSF
-
-Code contributions are most welcome. For any major edit (more than 15
-lines, or so, in aggregate per person), you need to make a copyright
-assignment to the Free Software Foundation. This is necessary because
-the themes are part of the upstream Emacs distribution: the FSF must at
-all times be in a position to enforce the GNU General Public License.
-
-Copyright assignment is a simple process. Check the request form below
-(please adapt it accordingly). You must write an email to the address
-mentioned in the form and then wait for the FSF to send you a legal
-agreement. Sign the document and file it back to them. This could all
-happen via email and take about a week. You are encouraged to go
-through this process. You only need to do it once. It will allow you
-to make contributions to Emacs in general.
-
-@example
-Please email the following information to assign@@gnu.org, and we
-will send you the assignment form for your past and future changes.
-
-Please use your full legal name (in ASCII characters) as the subject
-line of the message.

- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-0. PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document "free" in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of "copyleft", which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-
-
-1. APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The "Document", below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as "you". You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A "Modified Version" of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A "Secondary Section" is a named appendix or a front-matter section of
-the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The "Invariant Sections" are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-
-The "Cover Texts" are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A "Transparent" copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not "Transparent" is called "Opaque".
-
-Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, LaTeX input format, SGML
-or XML using a publicly available DTD, and standard-conforming simple
-HTML, PostScript or PDF designed for human modification. Examples of
-transparent image formats include PNG, XCF and JPG. Opaque formats
-include proprietary formats that can be read and edited only by
-proprietary word processors, SGML or XML for which the DTD and/or
-processing tools are not generally available, and the
-machine-generated HTML, PostScript or PDF produced by some word
-processors for output purposes only.
-
-The "Title Page" means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, "Title Page" means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-The "publisher" means any person or entity that distributes copies of
-the Document to the public.
-
-A section "Entitled XYZ" means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as "Acknowledgements",
-"Dedications", "Endorsements", or "History".) To "Preserve the Title"
-of such a section when you modify the Document means that it remains a
-section "Entitled XYZ" according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-
-2. VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no
-other conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-
-3. COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to
-give them a chance to provide you with an updated version of the
-Document.
-
-
-4. MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-
-A. Use in the Title Page (and on the covers, if any) a title distinct
- from that of the Document, and from those of previous versions
- (which should, if there were any, be listed in the History section
- of the Document). You may use the same title as a previous version
- if the original publisher of that version gives permission.
-B. List on the Title Page, as authors, one or more persons or entities
- responsible for authorship of the modifications in the Modified
- Version, together with at least five of the principal authors of the
- Document (all of its principal authors, if it has fewer than five),
- unless they release you from this requirement.
-C. State on the Title page the name of the publisher of the
- Modified Version, as the publisher.
-D. Preserve all the copyright notices of the Document.
-E. Add an appropriate copyright notice for your modifications
- adjacent to the other copyright notices.
-F. Include, immediately after the copyright notices, a license notice
- giving the public permission to use the Modified Version under the
- terms of this License, in the form shown in the Addendum below.
-G. Preserve in that license notice the full lists of Invariant Sections
- and required Cover Texts given in the Document's license notice.
-H. Include an unaltered copy of this License.
-I. Preserve the section Entitled "History", Preserve its Title, and add
- to it an item stating at least the title, year, new authors, and
- publisher of the Modified Version as given on the Title Page. If
- there is no section Entitled "History" in the Document, create one
- stating the title, year, authors, and publisher of the Document as
- given on its Title Page, then add an item describing the Modified
- Version as stated in the previous sentence.
-J. Preserve the network location, if any, given in the Document for
- public access to a Transparent copy of the Document, and likewise
- the network locations given in the Document for previous versions
- it was based on. These may be placed in the "History" section.
- You may omit a network location for a work that was published at
- least four years before the Document itself, or if the original
- publisher of the version it refers to gives permission.
-K. For any section Entitled "Acknowledgements" or "Dedications",
- Preserve the Title of the section, and preserve in the section all
- the substance and tone of each of the contributor acknowledgements
- and/or dedications given therein.
-L. Preserve all the Invariant Sections of the Document,
- unaltered in their text and in their titles. Section numbers
- or the equivalent are not considered part of the section titles.
-M. Delete any section Entitled "Endorsements". Such a section
- may not be included in the Modified Version.
-N. Do not retitle any existing section to be Entitled "Endorsements"
- or to conflict in title with any Invariant Section.
-O. Preserve any Warranty Disclaimers.
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled "Endorsements", provided it contains
-nothing but endorsements of your Modified Version by various
-parties--for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-
-5. COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled "History"
-in the various original documents, forming one section Entitled
-"History"; likewise combine any sections Entitled "Acknowledgements",
-and any sections Entitled "Dedications". You must delete all sections
-Entitled "Endorsements".
-
-
-6. COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other
-documents released under this License, and replace the individual
-copies of this License in the various documents with a single copy
-that is included in the collection, provided that you follow the rules
-of this License for verbatim copying of each of the documents in all
-other respects.
-
-You may extract a single document from such a collection, and
-distribute it individually under this License, provided you insert a
-copy of this License into the extracted document, and follow this
-License in all other respects regarding verbatim copying of that
-document.
-
-
-7. AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an "aggregate" if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-
-8. TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled "Acknowledgements",
-"Dedications", or "History", the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-
-9. TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-
-However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-
-Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-
-
-10. FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions of the
-GNU Free Documentation License from time to time. Such new versions
-will be similar in spirit to the present version, but may differ in
-detail to address new problems or concerns. See
-https://www.gnu.org/licenses/.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License "or any later version" applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation. If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy's public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-
-11. RELICENSING
-
-"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works. A
-public wiki that anybody can edit is an example of such a server. A
-"Massive Multiauthor Collaboration" (or "MMC") contained in the site
-means any set of copyrightable works thus published on the MMC site.
-
-"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-
-"Incorporate" means to publish or republish a Document, in whole or in
-part, as part of another Document.
-
-An MMC is "eligible for relicensing" if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole or
-in part into the MMC, (1) had no cover texts or invariant sections, and
-(2) were thus incorporated prior to November 1, 2008.
-
-The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.
-
-
-ADDENDUM: How to use this License for your documents
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-
- Copyright (c) YEAR YOUR NAME.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
- A copy of the license is included in the section entitled "GNU
- Free Documentation License".
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the "with...Texts." line with this:
-
- with the Invariant Sections being LIST THEIR TITLES, with the
- Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.
