2 What is Muse?
***************

Emacs Muse (also known as "Muse" or "Emacs-Muse") is an authoring and
publishing environment for Emacs.  It simplifies the process of writing
documents and publishing them to various output formats.

   Muse consists of two main parts: an enhanced text-mode for authoring
documents and navigating within Muse projects, and a set of publishing
styles for generating different kinds of output.

   What makes Muse distinct from other text-publishing systems is a
modular environment, with a rather simple core, in which "styles" are
derived from to create new styles.  Much of Muse's overall
functionality is optional.  For example, you can use the publisher
without the major-mode, or the mode without doing any publishing; or if
you don't load the Texinfo or LaTeX modules, those styles won't be
available.

   The Muse codebase is a departure from emacs-wiki.el version 2.44. The
code has been restructured and rewritten, especially its publishing
functions.  The focus in this revision is on the authoring and
publishing aspects, and the "wikiness" has been removed as a default
behavior (available in the optional `muse-wiki' module).  CamelCase
words are no longer special by default.

   One of the principal aims in the development of Muse is to make it
very easy to produce good-looking, standards-compliant documents.

3 How to Get Muse Releases and Development Changes
**************************************************

* Menu:

* Releases::                    Released versions of Muse.
* Development::                 Latest unreleased development changes.

\1f
File: muse.info,  Node: Releases,  Next: Development,  Prev: Obtaining Muse,  Up: Obtaining Muse

3.1 Released versions of Muse
=============================

Choose to install a release if you want to minimize risk.

   Errors are corrected in development first.  User-visible changes
will be announced on the <muse-el-discuss@gna.org> mailing list.  *Note
Getting Help and Reporting Bugs::.

   Debian users can get Muse via apt-get.  The `muse-el' package is
available both at Michael Olson's APT repository and the official Debian
repository.  To make use of the former, add the following line to your
`/etc/apt/sources.list' file and run `apt-get install muse'.

     deb http://mwolson.org/debian/ ./

   Ubuntu users can also get Muse via apt-get.  The `muse-el' package
is available both at Michael Olson's APT repository and the official
Ubuntu repository.  To make use of the former, add the following line to
your `/etc/apt/sources.list' file and run `apt-get install muse'.

     deb http://mwolson.org/ubuntu/ ./

   The reason for making separate Debian and Ubuntu packages is that
this manual is under the GFDL, and Debian will not allow it to be
distributed in its main repository.  Ubuntu, on the other hand, permits
this manual to be included with the `muse-el' package.

   Alternatively, you can download the latest release from
`http://download.gna.org/muse-el/' .

\1f
File: muse.info,  Node: Development,  Prev: Releases,  Up: Obtaining Muse

3.2 Latest unreleased development changes
=========================================

Choose the development version if you want to live on the bleeding edge
of Muse development or try out new features before release.

   The git version control system allows you to keep up-to-date with the
latest changes to the development version of Muse.  It also allows you
to contribute changes (via commits, if you are have developer access to
the repository, or via patches, otherwise).  If you would like to
contribute to Muse development, it is highly recommended that you use
git.

   If you are new to git, you might find this tutorial helpful:
`http://www.kernel.org/pub/software/scm/git/docs/tutorial.html'.

   Downloading the Muse module with git and staying up-to-date involves
the following steps.

  1. Install git.

        * Debian and Ubuntu: `apt-get install git-core'.

        * Windows: `http://git.or.cz/gitwiki/WindowsInstall'.

        * Other operating systems: download, compile, and install the
          source from `http://www.kernel.org/pub/software/scm/git/', or
          find a git package for your operating system.

  2. Download the Muse development branch.

     If you have developer access to Muse, do:

          git clone ssh://repo.or.cz/srv/git/muse-el.git muse

     otherwise, do:

          git clone git://repo.or.cz/muse-el.git muse

     If you are behind a restrictive firewall, and do not have developer
     access, then do the following instead:

          git clone http://repo.or.cz/r/muse-el.git muse

  3. List upstream changes that are missing from your local copy.  Do
     this whenever you want to see whether new changes have been
     committed to Muse.  If you wish, you may skip this step and
     proceed directly to the "update" step.

          # Change to the source directory you are interested in.
          cd muse

          # Fetch new changes from the repository, but don't apply them yet
          git fetch origin

          # Display log messages for the new changes
          git log HEAD..origin

     "origin" is git's name for the location where you originally got
     Muse from.  You can change this location at any time by editing the
     `.git/config' file in the directory where the Muse source was
     placed.

  4. Update to the latest version by pulling in any missing changes.

          cd muse
          git pull origin

     git will show how many files changed, and will provide a visual
     display for how many lines were changed in each file.


   There are other ways to interact with the Muse repository.

   * Browse git repo: `http://repo.or.cz/w/muse-el.git'

   * Latest development snapshot:
     `http://mwolson.org/static/dist/muse-latest.tar.gz'

   * Latest development snapshot (zip file):
     `http://mwolson.org/static/dist/muse-latest.zip'

   The latest development snapshot can lag behind the git repo by as
much as 20 minutes, but never more than that.

Becoming a Muse developer
-------------------------

If you want commit access to the shared Muse repository, then register
an account at `http://repo.or.cz' (be sure to add an SSH key), and
contact the current maintainer at <mwolson@gnu.org>.  It would be best
to send some patches to the <muse-el-discuss@gna.org> mailing list
first, so that he knows that you know what you are doing.  *Note
Getting Help and Reporting Bugs::, for instructions on subscribing to
the mailing list.

   You must also be willing to sign a copyright assignment for your
changes to Muse, since Muse is a GNU project.  The current maintainer
will assist you in this process if you contact him.

   For information on committing changes to Muse and performing
development, please consult
`http://emacswiki.org/cgi-bin/wiki/MuseDevelopment'.

4 Compiling and Installing Muse
*******************************

Muse may be compiled and installed on your machine.

Compilation
-----------

This is an optional step, since Emacs Lisp source code does not
necessarily have to be byte-compiled.  Byte-compilation may yield a very
slight speed increase.

   A working copy of Emacs or XEmacs is needed in order to compile Emacs
Muse.  By default, the program that is installed with the name `emacs'
will be used.

   If you want to use the `xemacs' binary to perform the compilation,
you must copy `Makefile.defs.default' to `Makefile.defs' in the
top-level directory, and then edit `Makefile.defs' as follows.  You can
put either a full path to an Emacs or XEmacs binary or just the command
name, as long as it is in the `PATH'.

     EMACS    = xemacs
     SITEFLAG = -no-site-file
     # Edit the section as necessary
     install_info = install-info --section "XEmacs 21.4" $(1).info \
             $(INFODIR)/dir || :

   Running `make' in the top-level directory should compile the Muse
source files in the `lisp' directory, and generate an autoloads file in
`lisp/muse-autoloads.el'.

Installation
------------

Muse may be installed into your file hierarchy by doing the following.

   Copy `Makefile.defs.default' to `Makefile.defs' in the top-level
directory, if you haven't done so already.  Then edit the
`Makefile.defs' file so that `ELISPDIR' points to where you want the
source and compiled Muse files to be installed and `INFODIR' indicates
where to put the Muse manual.  You may use a combination of `DESTDIR'
and `PREFIX' to further determine where the installed files should be
placed.  As mentioned earlier, you will want to edit `EMACS' and
`SITEFLAG' as shown in the Compilation section if you are using XEmacs.

   If you are installing Muse on a Debian or Ubuntu system, you might
want to change the value of `INSTALLINFO' as specified in
`Makefile.defs'.

   If you wish to install Muse to different locations than the defaults
specify, edit `Makefile.defs' accordingly.

   Run `make' as a normal user, if you haven't done so already.

   Run `make install' as the root user if you have chosen installation
locations that require root permissions.

ELPA
----

For those used to installing software packages, there will be a `muse'
package available in the Emacs Lisp Package Archive (abbreviated
"ELPA") as of the 3.10 release of Muse.  This package will be compiled
and installed automatically in a user-specific location.  For more
information on ELPA, see `http://tromey.com/elpa/'.

\1f
File: muse.info,  Node: Loading Muse,  Next: Using Muse Mode,  Prev: Getting Started,  Up: Getting Started

5.1 How to Load Muse
====================

To use Muse, add the directory containing its files to your `load-path'
variable, in your `.emacs' file.  Then, load in the authoring mode, and
the styles you wish to publish to.  An example follows.

     (add-to-list 'load-path "<path to Muse>")

     (require 'muse-mode)     ; load authoring mode

     (require 'muse-html)     ; load publishing styles I use
     (require 'muse-latex)
     (require 'muse-texinfo)
     (require 'muse-docbook)

     (require 'muse-project)  ; publish files in projects

   An easy way of seeing which settings are available and changing
settings is to use the Muse customization interface.  To do this, type
`M-x customize-group muse RET'.  Each of the options has its own
documentation.  Options are grouped logically according to what effect
they have.

\1f
File: muse.info,  Node: Using Muse Mode,  Next: Publishing Files Overview,  Prev: Loading Muse,  Up: Getting Started

5.2 How to Edit Files in Muse
=============================

Muse Mode should automatically be activated when you visit a file with a
".muse" extension.  One such file is `QuickStart.muse', which is
available in the `examples' directory of the Muse distribution.  You
can tell that Muse Mode has been activated by checking for the text
"Muse" in your mode line.  If Muse Mode has not been activated, you may
activate it by type `M-x muse-mode RET'.

   You will notice that Muse files are highlighted very simply.  Links
are colored blue, headings are large and bold text, and <example> tags
are colored in grey.

   There are several different ways to edit things like links, which
hide the underlying Muse markup.  One way is to toggle font-locking off
by hitting `C-c C-l', which is also `M-x font-lock-mode', make changes,
and then hit `C-c C-l' again to toggle font-locking back on.  Another
way is just to move into the text and edit it.  Markup can also be
removed by normal deletion methods, though some side effects might
require a second deletion.

   For the particular case of editing links, it is easiest to move to
the link and do `C-c C-e', which is also `M-x muse-edit-link-at-point'.
This prompts you for the link and its description, using the previous
contents of the link as initial values.  A link to another Muse file
may be created by hitting `C-c TAB l'.  A link to a URL may be created
by hitting `C-c TAB u'.  Links may be followed by hitting `RET' on them.

   If you want to add a new list item, this may by accomplished by
hitting `M-RET'.  This will put a dash and some spaces on the screen.
The dash is the Muse markup that indicates a list item.  It is also
possible to created "nested" lists with this command, by adjusting the
number of spaces in front of the dashes.  If you have lists with long
lines, you can move to a list item and hit `M-q' to wrap it onto
multiple lines.

\1f
File: muse.info,  Node: Publishing Files Overview,  Next: File Extensions,  Prev: Using Muse Mode,  Up: Getting Started

5.3 Publishing a Single File or Project
=======================================

The command `M-x muse-project-publish-this-file' will publish the
current document to any available publishing style (a publishing style
is an output format, like HTML or Docbook), placing the output in the
current directory.  If you are in Muse Mode, this command will be bound
to `C-c C-t'.  If the file has been published recently, and its
contents have not changed, running `C-c C-t' again will not publish the
file.  To force publishing in this case, do `C-u C-c C-t'.

   If you have set up projects and are visiting a file that is part of a
project, then `C-c C-t' will restrict the output formats to those which
are used by the project, and will automatically publish to the output
directory defined by the project.  If you want to publish to a
different directory or use a different format, then use `C-c M-C-t',
which is also `M-x muse-publish-this-file'.

   If the currently opened file is part of a defined project in
`muse-project-alist', it (and the rest of the changed files in a
project) may be published using `C-c C-p'.

\1f
File: muse.info,  Node: File Extensions,  Prev: Publishing Files Overview,  Up: Getting Started

5.4 Using a Different File Extension
====================================

By default, Muse expects all project files to have the file extension
`.muse'. Files without this extension will not be associated with Muse
mode and will not be considered part of any project, even if they are
within a project directory.

   If you don't want to use `.muse', you can customize the extension by
setting the value of `muse-file-extension'.

   If you don't want to use any extension at all, and want Muse to
autodetect project files based on their location, then add the following
to your Muse settings file.

     (setq muse-file-extension nil
           muse-mode-auto-p t)

   Note that if you chose to have `muse-file-extension' set to `nil',
you may have trouble if your `.emacs' file or other init scripts
attempt to visit a Muse file.  (A very common example of this is if you
use Planner with Muse and run `(plan)' from your `.emacs'.)  If you
wish to visit Muse files from your `.emacs', be sure to also add the
following additional code before any such visits happen:

     (add-hook 'find-file-hooks 'muse-mode-maybe)

6 Creating and Managing Muse Projects
*************************************

Often you will want to publish all the files within a directory to a
particular set of output styles automatically.  To support, Muse allows
for the creation of "projects".

* Menu:

* Single Project::              A single-project example.
* Multiple Projects::           A multiple-project example.
* Projects and Subdirectories::  Publishing subdirectories in projects.
* Options for Projects::        Listing of available options for projects.

\1f
File: muse.info,  Node: Single Project,  Next: Multiple Projects,  Prev: Projects,  Up: Projects

6.1 A Single-Project Example
============================

Here is a sample project, which may be defined in your `.emacs' file.

     (setq muse-project-alist
           '(("Website" ("~/Pages" :default "index")
              (:base "html" :path "~/public_html")
              (:base "pdf" :path "~/public_html/pdf"))))

   The above defines a project named "website", whose files are located
in the directory `~/Pages'.  The default page to visit is `index'.
When this project is published, each page will be output as HTML to the
directory `~/public_html', and as PDF to the directory
`~/public_html/pdf'.  Within any project page, you may create a link to
other pages using the syntax `[[pagename]]'.

   If you would like to include only some files from a directory in a
Muse project, you may use a regexp in place of `~/Pages' in the example.

6.2 A Multiple-Project Example
==============================

It is possible to specify multiple projects.  Here is an example of
three projects: a generic website, a projects area, and a day-planner
(the day-planner part requires Planner Mode--see
`http://wjsullivan.net/PlannerMode.html' to get it).

     (setq muse-project-alist
           '(("Website" ("~/Pages" :default "index")
              (:base "html" :path "~/public_html"))
             (("Projects" ("~/Projects" :default "index")
              (:base "xhtml"
                     :path "~/public_html/projects"
                     :exclude "/TopSecret")
              (:base "pdf"
                     :path "~/public_html/projects/pdf"
                     :exclude "/TopSecret")))
             ("Plans" ("~/Plans"
                       :default "TaskPool"
                       :major-mode planner-mode
                       :visit-link planner-visit-link)
              (:base "planner-xhtml"
                     :path "~/public_html/plans"))))

   The `:major-mode' attribute specifies which major to use when
visiting files in this directory.

   The `:visit-link' attribute specifies the function to call when
visiting links.

   The `:exclude' attribute has a regexp that matches files to never
publish.

6.3 Publishing Subdirectories in Projects
=========================================

If you want to publish a directory and all of its subdirectories, Muse
provides two convenience functions that together generate the proper
rules for you.  Note that we use the backtick to begin this
muse-project-alist definition, rather than a single quote.

     (setq muse-project-alist
           `(("Website" ("~/Pages" :default "index")
              (:base "html" :path "~/public_html"))
             ("Blog" (,@(muse-project-alist-dirs "~/Blog")
                      :default "index")
              ;; Publish this directory and its subdirectories.  Arguments
              ;; are as follows.  The above `muse-project-alist-dirs' part
              ;; is also needed.
              ;;   1. Source directory
              ;;   2. Output directory
              ;;   3. Publishing style
              ;;   remainder: Other things to put in every generated style
              ,@(muse-project-alist-styles "~/Blog"
                                           "~/public_html/blog"
                                           "blosxom"))))

   The `muse-project-alist-dirs' function takes a directory and returns
it and all of its subdirectories in a list.

   The `muse-project-alist-styles' function is explained by the
comments above.

   The "blosxom" text is the name of another publishing style, much like
"html".  *Note Blosxom::, for further information about it.  You can
use any publishing style you like for the third argument to
`muse-project-alist-styles'.

6.4 Listing of Available Options for Projects
=============================================

This is a listing of all of the various options (or, more accurately:
attributes) that may be specified in `muse-project-alist'.

   Each muse-project-alist entry looks like this:

       (PROJECT-NAME (SOURCES)
         OUTPUTS)

   We refer to these names below.

   "Attributes", which compose SOURCES and OUTPUTS, are a pair of
values.  The first value is a keyword, like `:default'.  The second part
is the value associated with that keyword, such as the text "index".
If you are familiar with Emacs Lisp property lists, the concept is
similar to that, except that in the SOURCES section, single directories
can be interspersed with two-value attributes.

Project Name
------------

This is a string that indicates the name of the project.  It is
primarily used for publishing interwiki links with the `muse-wiki.el'
module.

Sources
-------

This part of a muse-project-alist entry consists of two-value
attributes, and also directory names.  If you are publishing a book, the
order of directories and attributes is significant.

   The minimal content for the sources section is a list of directories.

`:book-chapter'
     Indicates a new chapter of a book.  The text of the title of the
     chapter comes immediately after this keyword.

`:book-end'
     Indicates the end of a book.  Directories listed after this one are
     ignored when publishing a book.  The value "t" (without quotes)
     should come immediately after this keyword.

`:book-funcall'
     A function to call while publishing a book.  This is useful for
     doing something just after a particular chapter.

`:book-part'
     Indicates the beginning of a new part of the book.  The text of the
     title should come immediately after this keyword.

`:book-style'
     Indicate a particular publishing style to use for this part of the
     book.  If this is specified, it should come just after a `:part'
     attribute.

`:default'
     The default page to visit when browsing a project.  Also, if you
     are using the `muse-wiki.el' module, publishing a link to just a
     project's name will cause it to link to this default file.

`:force-publish'
     This specifies a list of pages which should be published every
     time a project is published (by using `C-c C-p', for example),
     regardless of whether their contents have changed.  This is useful
     for updating Index pages, pages that use the <include> tag, and
     other pages that have dynamically-generated content.

`:major-mode'
     This specifies the major mode to use when visiting files in this
     project.  The default is `muse-mode'.

`:nochapters'
     This indicates that while publishing a book, do not automatically
     create chapters.  Values which may follow this are nil (the
     default, which means that we automatically create chapters), or
     non-nil, which means that we manually specify chapters with the
     `:book-chapter' attribute,

`:publish-project'
     Indicates which function we should call when publishing a project.

`:set'
     This specifies a list of variables and values to set when
     publishing a project.  The list should be a property list, which
     is in the form:

          (VAR1 VALUE1 VAR2 VALUE2 ...)

`:visit-link'
     Specifies the function to call when visiting a link.  The default
     is `muse-visit-link-default'.  The arguments for that function
     should be (1) the link and (2) whether to visit the link in a new
     window.


Outputs
-------

This part of a muse-project-alist entry is composed of lists of
attributes.  Each list is called an "output style".

   The minimal content for an output style is a `:base' attribute and a
`:path' attribute.

`:base'
     Publishing style to use, such as "html", "docbook", or "pdf".

`:base-url'
     An external URL which can be used to access published files.  This
     is mainly used by the `muse-wiki' module when publishing links
     between two separate projects, if the projects are served on
     different domains.

     It is also used by the `muse-journal' module to create the RSS or
     RDF output.

`:exclude'
     Exclude items matching a regexp from being published.  The regexp
     should usually begin with "/".

`:include'
     Only include items matching a regexp when publishing.  The regexp
     should usually begin with "/".

`:path'
     The directory in which to store published files.

`:timestamps'
     A file containing the timestamps (that is, time of creation) for
     files in this project.  It might eventually used by the
     `muse-blosxom' module, but this option is not currently in use by
     any Muse code.

8 Rules for Using Markup
************************

A Muse document uses special, contextual markup rules to determine how
to format the output result.  For example, if a paragraph is indented,
Muse assumes it should be quoted.

   There are not too many markup rules, and all of them strive to be as
simple as possible so that you can focus on document creation, rather
than formatting.

8.1 Paragraphs: centering and quoting
=====================================

Paragraphs in Muse must be separated by a blank line.

Centered paragraphs and quotations
----------------------------------

A line that begins with six or more columns of whitespace (either tabs
or spaces) indicates a centered paragraph.  Alternatively, you can use
the <center> tag to surround regions that are to be published as
centered paragraphs.

   But if a line begins with whitespace, though less than six columns,
it indicates a quoted paragraph.  Alternatively, you can use the
<quote> tag to surround regions that are to be published as quoted
paragraphs.

Literal paragraphs
------------------

The <example> tag is used for examples, where whitespace should be
preserved, the text rendered in monospace, and any characters special
to the output style escaped.

   There is also the <literal> tag, which causes a marked block to be
entirely left alone.  This can be used for inserting a hand-coded HTML
blocks into HTML output, for example.

   If you want some text to only be inserted when publishing to a
particular publishing style, use the `style' attribute for the
<literal> tag.  An example follows.

     <literal style="latex">
     A LaTeX-based style was used in the publishing of this document.
     </literal>

   This will leave the region alone if the current publishing style is
"latex" or based on "latex", such as "pdf", and delete the region
otherwise.  It is also possible to leave the text alone only for one
particular style, rather than its derivations, by adding `exact="t"' to
the tag.

Line breaks
-----------

If you need a line break, then use the `<br>' tag.  Most of the time
this tag is unnecessary, because Muse will automatically detect
paragraphs by means of blank lines.  If you want to preserve newlines in
several lines of text, then use verse markup instead (*note Verse::).

8.2 Levels of headings
======================

A heading becomes a chapter or section in printed output - depending on
the style.  To indicate a heading, start a new paragraph with one or
more asterices, followed by a space and the heading title.  Then begin
another paragraph to enter the text for that section.

   All levels of headings will be published.  Most publishing styles
only distinguish the between the first 4 levels, however.

     * First level

     ** Second level

     *** Third level

     **** Fourth level

\1f
File: muse.info,  Node: Directives,  Next: Emphasizing Text,  Prev: Headings,  Up: Markup Rules

8.3 Directives at the beginning of a document
=============================================

Directives are lines beginning with the `#' character that come before
any paragraphs or sections in the document.  Directives are of the form
"#directive content of directive".  You can use any combination of
uppercase and lowercase letters for directives, even if the directive
is not in the list below.

   The `muse-publishing-directive' function may be used in header and
footer text to access directives.  For example, to access the `#title'
directive, use `(muse-publishing-directive "title")'.

   The following is a list of directives that Muse uses.

`#author'
     The author of this document.

     If this is not specified, Muse will attempt to figure it out from
     the `user-full-name' variable.

`#date'
     The date that the document was last modified.

     This is used by publishing styles that are able to embed the date
     information.

`#desc'
     A short description of this document.

     This is used by the `journal' publishing style to embed information
     inside of an RSS/RDF feed.

`#title'
     The title of this document.

     If this is not specified, the name of the file is used.


\1f
File: muse.info,  Node: Emphasizing Text,  Next: Footnotes,  Prev: Directives,  Up: Markup Rules

8.4 Bold, italicized, and underlined text
=========================================

To emphasize text, surround it with certain specially recognized
characters.

     *emphasis*
     **strong emphasis**
     ***very strong emphasis***
     _underlined_
     =verbatim and monospace=

   While editing a Muse document in Muse mode, these forms of emphasis
will be highlighted in a WYSIWYG manner.  Each of these forms may span
multiple lines.

   Verbatim text will be colored as gray by default.  To change this,
customize `muse-verbatim-face'.

   You can also use the <code> tag to indicate verbatim and monospace
text.  This is handy for regions that have an "=" in them.

File: muse.info,  Node: Footnotes,  Next: Verse,  Prev: Emphasizing Text,  Up: Markup Rules

8.5 Making notes to be shown at the end
=======================================

A footnote reference is simply a number in square brackets.  To define
the footnote, place this definition at the bottom of your file.
`footnote-mode' can be used to greatly facilitate the creation of these
kinds of footnotes.

   Footnotes are defined by the same number in brackets occurring at the
beginning of a line.  Use footnote-mode's `C-c ! a' command, to very
easily insert footnotes while typing.  Use `C-x C-x' to return to the
point of insertion.

\1f
File: muse.info,  Node: Verse,  Next: Lists,  Prev: Footnotes,  Up: Markup Rules

8.6 Indicating poetic stanzas
=============================

Poetry requires that whitespace be preserved, but without resorting to
monospace.  To indicate this, use the following markup, reminiscent of
email quotations.

     > A line of Emacs verse;
     >   forgive its being so terse.

   You can also use the <verse> tag, if you prefer.

     <verse>
     A line of Emacs verse;
       forgive its being so terse.
     </verse>

   Multiple stanzas may be included in one set of <verse> tags, as
follows.

     <verse>
     A line of Emacs verse;
       forgive its being so terse.

     In terms of terse verse,
       you could do worse.
     </verse>

\1f
File: muse.info,  Node: Lists,  Next: Tables,  Prev: Verse,  Up: Markup Rules

8.7 Lists of items
==================

Lists are given using special characters at the beginning of a line.
Whitespace must occur before bullets or numbered items, to distinguish
from the possibility of those characters occurring in a real sentence.

   These are rendered as a bullet list.

     Normal text.

      - bullet item one
      - bullet item two

   An enumerated list follows.

     Normal text.

      1. Enum item one
      2. Enum item two

   Here is a definition list.

     Term1 ::
       This is a first definition
       And it has two lines;
       no, make that three.

     Term2 :: This is a second definition

Nested lists
------------

It is possible to nest lists of the same or different kinds.  The
"level" of the list is determined by the amount of initial whitespace.

     Normal text.

      - Level 1, bullet item one
        1. Level 2, enum item one
        2. Level 2, enum item two
      - Level 1, bullet item two
        1. Level 2, enum item three
        2. Level 2, enum item four
           term :: definition

Breaking list items
-------------------

If you want to break up a line within any list type, just put one blank
line between the end of the previous line and the beginning of the next
line, using the same amount of initial indentation.

      - bullet item 1, line 1

        bullet item 1, line 2

        1. Enum line 1

           Enum line 2

      - bullet item 2, line 1

        bullet item 2, line 2

\1f
File: muse.info,  Node: Tables,  Next: Explicit Links,  Prev: Lists,  Up: Markup Rules

8.8 Generation of data tables
=============================

Only very simple tables are supported.  The syntax is as follows.

     Double bars  || Separate header fields

     Single bars   | Separate body fields
     Here are more | body fields

     Triple bars ||| Separate footer fields

   Some publishing styles require header fields to come first, then
footer fields, and then the body fields.  You can use any order for
these sections that you like, and Muse will re-order them for you at
publish-time.

   If you wish to disable table generation for one Muse file, add the
directive `#disable-tables t' to the top of the file.

Other table formats
-------------------

It is possible to publish very basic Orgtbl-mode style tables.

     | org  | style | table |
     |------+-------+-------|
     | one  |       | one   |
     | two  | two   |       |
     |      | three | three |
     |------+-------+-------|
     | more | stuff |       |

   If you are used to the way that Org Mode publishes these tables, then
customize `muse-html-table-attributes' to the following, in order to get
a similar kind of output.

     border="2" cellspacing="0" cellpadding="6" rules="groups" frame="hsides"

   `table.el' style tables are also supported, as long as `table.el'
itself supports outputting tables for a particular publishing style.
At the time of this writing, the "html", "latex", and "docbook" styles
are supported by `table.el'.  Styles derived from these styles will
also work.

     +---+-----+---+
     |   | one | 1 |
     +---+-----+---+
     | b | two |   |
     +---+-----+---+
     | c |     | 3 |
     +---+-----+---+

8.9 Hyperlinks and email addresses with descriptions
====================================================

A hyperlink can reference a URL, or another page within a Muse project.
In addition, descriptive text can be specified, which should be
displayed rather than the link text in output styles that supports link
descriptions.  The syntax is as follows.

     [[link target][link description]]
     [[link target without description]]

   Thus, the current maintainer's homepage for Muse can be found
`[[http://mwolson.org/projects/EmacsMuse.html][here]]', or at
`[[http://mwolson.org/projects/EmacsMuse.html]]'.

File: muse.info,  Node: Implicit Links,  Next: Images,  Prev: Explicit Links,  Up: Markup Rules

8.10 Bare URLs, WikiNames, and InterWiki links
==============================================

A URL or email address encountered in the input text is published as a
hyperlink.  These kind of links are called "implicit links" because
they are not separated from the rest of the Muse document in any way.

   Some characters in URLs will prevent Muse from recognizing them as
implicit links. If you want to link to a URL containing spaces or any of
the characters "][,"'`()<>^", you will have to make the link explicit.
The punctuation characters ".,;:" are also not recognized as part of a
URL when they appear at its end. For information on how to make an
explicit link, see *note Hyperlinks and email addresses with
descriptions: Explicit Links.

   If the `muse-wiki' module is loaded, another form of implicit link
will be made available.  WikiNames, which are typed in CamelCase, are
highlighted and published as links, provided that the file they refer
to exists.

   Customization of WikiName recognition may be accomplished by editing
the `muse-wiki-wikiword-regexp' option and subsequently running
`(muse-configure-highlighting 'muse-colors-markupmuse-colors-markup)'.
If you use the Customize interface, the latter will be done
automatically.

   The `muse-wiki' module also allows for InterWiki links.  These are
similar to WikiWords, but they specify both the project and page of a
file.  The names of your project entries in `muse-project-alist' will
be used as InterWiki names by default.  Several examples follow.

     Blog::DocumentingMuse
     Projects#EmacsMuse
     Website

   In the first case, the interwiki delimiter is `::', `Blog' is the
project name, and `DocumentingMuse' is the page name.  In the second
example, `#' is the interwiki delimiter.  If the name of a project
occurs by itself in text, like the third case, it will be colorized and
published as a link to the default page of the given project.

   Customization of interwiki links may be accomplished by editing the
`muse-wiki-interwiki-alist' option.

   It is also possible to link to an anchor in an interwiki document.
This is called a "three-part link".  Examples of this follow.

     Blog::DocumentingMuse#anchor1
     Projects#EmacsMuse#anchor2

8.11 Publishing and displaying images
=====================================

Image links
-----------

Links to images may be used in either the target or the description, or
both.  Thus, the following code will publish as a clickable image that
points to `http://mwolson.org/'.

     [[http://mwolson.org/][/static/logos/site-logo.png]]

   Normally, images in the link part will be inlined.

   If you want these images to be published as links instead, place the
text "URL:" immediately in front of the link text.  An example follows.

     [[URL:http://mwolson.org/static/logos/site-logo.png]]

Displaying images in Muse mode
------------------------------

If a link to a locally-available image is encountered in the link
description, Muse mode will attempt to display it if your version of
Emacs permits this.

   This behavior may be toggled with `C-c C-i', or disabled permanently
by setting the `muse-colors-inline-images' option to `nil'.

   The method for finding images may be altered by customizing the
`muse-colors-inline-image-method' option.  One useful value for this
option is `muse-colors-use-publishing-directory', which tells Muse mode
to look in the directory where the current file will be published.  The
default is to look in the current directory.  Relative paths like
`../pics/' should work for either setting.

   Eventually, it is hoped that Muse will be able to copy images from
the a "source" directory to a publishing directory by customizing
`muse-project-alist', but this has not been implemented yet.

Publishing simple images
------------------------

The following example will display correctly and publish correctly if a
PNG file called `TestLogo.png' exists in the `../pics/' directory.  If
text is on the same line as the picture, it will remain so in the
output.

     [[../myimage.png]]

Publishing images with captions
-------------------------------

If you want to add a caption to an image, use the following syntax.
This will center the image (if the output format supports it) and add a
centered caption below the picture.  Formats that do not support
centering the image will instead leave it against the left margin.

     [[../pics/mycat.png][My cat Dexter]]

   Images with captions may only occur in their own paragraphs, with no
text on the same line.  Otherwise, the published output will not be
syntactically correct.

8.12 Inserting a horizontal line or anchor
==========================================

Horizontal Rules
----------------

Four or more dashes indicate a horizontal rule.  Be sure to put blank
lines around it, or it will be considered part of the proceeding or
following paragraph!

Anchors
-------

If you begin a line with "#anchor" - where "anchor" can be any word
that doesn't contain whitespace - it defines an anchor at that point
into the document.  This point can be referenced using "page#anchor" as
the target in a Muse link.

8.13 Evaluating Emacs Lisp code in documents for extensibility
==============================================================

Arbitrary kinds of markup can be achieved using the <lisp> tag.  With
the <lisp> tag, you may generate whatever output text you wish.  The
inserted output will get marked up if the <lisp> tag appears within the
main text of the document.

     <lisp>(concat "This form gets " "inserted")</lisp>

   Note that you should not use the `insert' command within a set of
<lisp> tags, since the return value from the <lisp> tags will be
automatically inserted into the document.

   It is also possible to treat the output as if it were surrounded by
the <example>, <src>, or <verse> tags, by specifying "example", "src",
or "verse" as the `markup' attribute of the <lisp> tag.

     <lisp markup="example">
     (concat "Insert" " me")
     </lisp>

   Other languages also have tags that cause source code to be
evaluated.  *Note Tag Summary::, for details.

8.14 Support for citing other resources
=======================================

Example
-------

Here is an example of what citations look like in a Muse document.

     #bibsource REFDB

     * Title
     ** Subtitle

     Some text before <cite>Miller1999</cite> and after the citation.

     This is an author-only citation <cite type="author">Miller1999</cite>.

     And this is a year-only citation <cite type="year">Miller1999</cite>.

     Finally, this is a multi-head citation
     <cite>Miller1999,Andrews2005</cite>.

Overview
--------

The `#bibsource' directive defines the source of the bibliographies.
The following sources are possible.

   * DocBook + RefDB: the string "REFDB"

   * LaTeX + bibtex: the name of an appropriate bibtex file

   * LaTeX + RefDB: if the input file is called "foo.muse", then set
     this to "foo.bib"

   Citations are encoded as <cite> elements which enclose the citation
keys as they are defined in the bibliography file or database.  In
multi-head citations, the citation keys have to be separated by colons
or semicolons.  The `latex' and `docbook' styles translate these to the
proper separator automatically.

   The <cite> elements take an optional "type" attribute that defines
how the citation is rendered.  If the attribute is missing, you'll get
a regular citation according to the bibliography style, e.g." (Miller
et al., 1999)".  If the attribute is set to "author", only the name of
the author(s) will be rendered.  Accordingly, "year" will cause the
year to be printed.  This is useful to create citations like this:

     Miller et al. had already shown in a previous publication (1999) that
     this is not going to work.

   Remember that refdb-mode (the Emacs interface to RefDB) can retrieve
references by simply marking the citation key and running the
`refdb-getref-by-field-on-region' command.  Later versions of
`refdb-mode' will also allow to insert references as Muse citations
(which is already implemented for DocBook, TEI, and LaTeX documents).

   You may have noticed that there is no element to indicate the
position of the bibliography.  The latter is always created at a valid
position close to the end of the document.  The functions
`muse-docbook-bibliography' and `muse-latex-bibliography' are called in
the header or footer to generate this content, so it is possible to
change the exact position.

8.15 Lines to omit from published output
========================================

Use the following syntax to indicate a comment.  Comments will not be
published.

     ; Comment text goes here.

   That is, only a semi-colon at the beginning of a line, followed by a
literal space, will cause that line to be treated as a comment.

   You can alternatively surround the region with the <comment> tag.

   If you wish the comment to be published, but just commented out using
the comment syntax of the output format, then set
`muse-publish-comments-p' to non-nil.

8.16 Tags that Muse recognizes
==============================

Muse has several built-in tags that may prove useful during publishing.
*Note muse-publish-markup-tags::, to see how to customize the tags that
Muse uses, as well as make your own tags.

   Only a small subset of these tags are available in header and footer
text.  The `muse-publish-markup-header-footer-tags' option lists the
tags that are allowed in headers and footers.

Syntax
------

If a tag takes arguments, it will look like this, where "tagname" is
the name of the tag.

     <tagname arg1="string1" arg2="string2">

   If you want the tag to look like it came straight from an XHTML
document, you can alternatively do the following.

     <tagname arg1="string1" arg2="string2" />

   If a tag surrounds some text, it will look like this.

     <tagname>Some text</tagname>

   If a tag surrounds a large region, it will look like this.

     <tagname>
     Some text.
     Some more text.
     </tagname>

Tag listing
-----------

This is the complete list of tags that Muse accepts, including those
that were mentioned in previous sections.

`<br>'
     Insert a line break.

     Muse will automatically detect paragraphs when publishing by means
     of blank lines, so this tag is usually unnecessary.

`<cite>'
     Insert a citation to another source.

     This takes the argument `type', which indicates the type of
     citation.  The valid types are "author" and "year".  If this
     argument is omitted, include both author and year in the citation.

     The bibliography to use for the citation may be specified by the
     `#bibsource' directive.

     *Note Citations::, for additional information.

`<class>'
     If publishing to HTML, surround the given text with a <span> tag.
     It takes one argument called "name" that specifies the "class"
     attribute of the <span> tag.

     If publishing to a different format, do nothing extra to the text.

`<code>'
     Treat the text surrounded by the tag as if they were enclosed in
     equal signs, that is, make it monospace.

`<command>'
     Run a command on the region, replacing the region with the result
     of the command.  The command is specified with the "interp"
     argument.  If no value for "interp" is given, pass the entire
     region to the shell.

     The "markup" argument controls how this section is marked up.

     If it is omitted, publish the region with the normal Muse rules.

     If "nil", do not mark up the region at all, but prevent Muse from
     further interpreting it.

     If "example", treat the region as if it was surrounded by the
     <example> tag.

     If "src", treat the included text as if it was surrounded by the
     <src> tag.  You should also specify the "lang" attribute if doing
     this.

     If "verse", treat the region as if it was surrounded by the
     <verse> tag, to preserve newlines.

     Otherwise, it should be the name of a function to call, with the
     buffer narrowed to the region.

`<comment>'
     Treat the entire region as a comment.  If the option
     MUSE-PUBLISH-COMMENTS-P is nil, delete the region, otherwise
     publish it using the comment syntax of the current publishing
     style.

`<contents>'
     Publish a Table of Contents.  This will either be inserted
     in-place or at the beginning of the document, depending on your
     publishing style.  It does not have a delimiting tag.

     By default, only 2 levels of headings will be included in the
     generated Table of Contents.  To change this globally, customize
     the MUSE-PUBLISH-CONTENTS-DEPTH option.  To change this only for
     the current tag, use the "depth" argument.

`<div>'
     Insert a <div> tag into HTML documents, and do not insert anything
     special for other non-HTML publishing formats.

     If the "style" argument is provided, include it with the published
     <div> tag.  Likewise for the "id" argument.

`<example>'
     Publish the region in monospace, preserving the newlines in the
     region.  This is useful for snippets of code.

`<include>'
     Insert the given file at the current location during publishing.
     The basic use of this tag is as follows, replacing "included_file"
     with the name of the file that you want to include.

          <include file="included_file">

     The "markup" argument controls how this section is marked up.

     If it is omitted, publish the included text with the normal Muse
     rules.

     If "nil", do not mark up the included text at all.

     If "example", treat the included text as if it was surrounded by
     the <example> tag.

     If "src", treat the included text as if it was surrounded by the
     <src> tag.  You should also specify the "lang" attribute if doing
     this.

     If "verse", treat the included text as if it was surrounded by the
     <verse> tag, to preserve newlines.

     Otherwise, it should be the name of a function to call after
     inserting the file with the buffer narrowed to the section
     inserted.

`<lisp>'
     Evaluate the Emacs Lisp expressions between the initial and ending
     tags.  The result is then inserted into the document, so you do
     not need to explicitly call `insert'.  All text properties are
     removed from the resulting text.

     This tag takes the "markup" argument.  See the description of
     <command> for details.

`<literal>'
     Make sure that the text enclosed by this tag is published without
     escaping it in any way.  This is useful for inserting markup
     directly into the published document, when Muse does not provide
     the desired functionality.

`<markup>'
     Mark up the text between the initial and ending tags.  The markup
     command to use may be specified by the "function" argument.  The
     standard Muse markup routines are used by default if no "function"
     argument is provided.

     This is useful for marking up regions in headers and footers.  One
     example that comes to mind is generating a published index of all
     of the files in the current project by doing the following.

          <markup><lisp>(muse-index-as-string t t)</lisp></markup>

`<perl>'
     Run the `perl' language interpreter on the region, replacing the
     region with the result of the command.

     This tag takes the "markup" argument.  See the description of
     <command> for details.

`<python>'
     Run the `python' language interpreter on the region, replacing the
     region with the result of the command.

     This tag takes the "markup" argument.  See the description of
     <command> for details.

`<quote>'
     Publish the region as a blockquote.  This will either be inserted
     in-place or at the beginning of the document, depending on your
     publishing style.  It does not have a delimiting tag.

`<ruby>'
     Run the `ruby' language interpreter on the region, replacing the
     region with the result of the command.

     This tag takes the "markup" argument.  See the description of
     <command> for details.

`<src>'
     Publish the region using htmlize.  The language to use may be
     specified by the "lang" attribute.

     Muse will look for a function named LANG-mode, where LANG is the
     value of the "lang" attribute.

     This tag requires htmlize 1.34 or later in order to work.  If this
     is not satisfied, or the current publishing style is not
     HTML-based, Muse will publish the region like an <example> tag.

`<verbatim>'
     This is used when you want to prevent Muse from trying to
     interpret some markup.  Surround the markup in <verbatim> and
     </verbatim>, and it will not be interpreted.

     This tag was used often in previous versions of Muse because they
     did not support whole-document escaping of specials.  Now, it will
     only be needed for other tags, and perhaps footnotes as well.

`<verse>'
     Preserve the newlines in the region.  In formats like HTML,
     newlines are removed by default, hence the need for this tag.  In
     other publishing styles, this tag may cause the text to be
     indented slightly in a way that looks nice for poetry and prose.

\1f
File: muse.info,  Node: Blosxom Requirements,  Next: Blosxom Entries,  Prev: Blosxom,  Up: Blosxom

9.1.1 Other tools needed for the Blosxom style
----------------------------------------------

You will need to have `pyblosxom.cgi' or `blosxom.cgi' installed on a
machine that you have upload access to.

   The major difficulty in both of these programs is specifying the
date of the entries.  Both programs rely on the file modification time
rather than any data contained in the entries themselves.  A plugin is
needed in order for these programs to be able to get the correct date.

PyBlosxom
---------

There are two different ways of accomplishing this in pyblosxom.  The
first way involves gathering the timestamps (as specified by the
`#date' directive) into one file and then sending that file along with
published entries to the webserver.

   The second will read each file at render time and parse the
`#postdate' directive.  Muse will translate the `#date' directive into
`#postdate' at publish time, so you don't have to do any extra work.

Placing timestamps in one file
..............................

The following additional components are required in order to make the
date of blog entries display as something sensible.

  1. A script to gather date directives from the entire blog tree into a
     single file.  The file must associate a blog entry with a date.

  2. A plugin for (py)blosxom that reads this file.

   These 2 things are provided for `pyblosxom.cgi' in the
`contrib/pyblosxom' subdirectory.  `getstamps.py' provides the former
service, while `hardcodedates.py' provides the latter service.

   Here is a sample listing from my `timestamps' file, which maps each
file to a date.  This can really be in any format, as long as your
date-gathering script and your plugin can both understand it.

     2005-04-01-14-16 personal/paper_cranes
     2005-03-21 personal/spring_break_over
     2004-10-24 personal/finished_free_culture

   The script `contrib/pyblosxom/make-blog' demonstrates how to call
`getstamps.py'.  Note that you will need to set the current directory
to where your Muse files are, execute `getstamps.py', and then move the
generated timestamps file to your publishing directory.

Getting timestamp from entry while rendering
............................................

Alternately, the pyblosxom metadate plugin may be used.  On the plus
side, there is no need to run a script to gather the date.  On the
downside, each entry is read twice rather than once when the page is
rendered.  Set the value of `muse-blosxom-use-metadate' to non-nil to
enable adding a `#postdate' directive to all published files.  You can
do this by:

     M-x customize-variable RET muse-blosxom-use-metadate RET

   With the metadate plugin installed in pyblosxom, the date set in this
directive will be used instead of the file's modification time.  The
plugin is included with Muse at `contrib/pyblosxom/metadate.py'.

Blosxom
-------

It is also possible to use Blosxom, which is written in Perl, to serve
blog entries that were published with Muse.  The steps are as follows.

  1. Download and install blosxom from
     `http://blosxom.sourceforge.net/'.

  2. Install the metadate plugin.  It is available in
     `contrib/blosxom/metadate_0_0_3'.

  3. Every time you make a new blog entry, change to the blosxom data
     directory and execute the `contrib/blosxom/getstamps.pl' script.
     This script has only recently been made, and may still have some
     bugs, so use with caution.

9.1.2 Format of a Blosxom entry and automation
----------------------------------------------

Each Blosxom file must include `#date yyyy-mm-dd', or optionally the
longer `#date yyyy-mm-dd-hh-mm', a title (using the `#title'
directive), plus whatever normal content is desired.

   The date directive is not used directly by `pyblosxom.cgi' or this
program.  You need to have the two additional items from the former
section to make use of this feature.

   There is a function called `muse-blosxom-new-entry' that will
automate the process of making a new blog entry.  To make use of it, do
the following.

   * Customize `muse-blosxom-base-directory' to the location that your
     blog entries are stored.

   * Assign the `muse-blosxom-new-entry' function to a key sequence.  I
     use the following code to assign this function to `C-c p l''.

          (global-set-key "\C-cpl" 'muse-blosxom-new-entry)

   * You should create your directory structure ahead of time under
     your base directory.  These directories, which correspond with
     category names, may be nested.

   * When you enter this key sequence, you will be prompted for the
     category of your entry and its title.  Upon entering this
     information, a new file will be created that corresponds with the
     title, but in lowercase letters and having special characters
     converted to underscores.  The title and date directives will be
     inserted automatically.

9.2 Publishing entries into a compilation
=========================================

This publishing style is used to output "books" in LaTeX or PDF format.

   Each page will become a separate chapter in the book, unless the
style keyword `:nochapters' is used, in which case they are all run
together as if one giant chapter.

   One way of publishing a book is to make a project for it, add the
project to `muse-project-alist', and use the `book-pdf' style with a
very specific `:include' value to specify some page whose contents will
be checked for the values of `#title' and `#date', and whose name will
be used in the output file.  Then to publish the book, visit the
aforementioned page and use `C-c C-t' or `C-c C-p' to trigger the
publishing process.  An example `muse-project-alist' for this method
follows.

     (setq muse-project-alist
           '(("MyNotes" (:nochapters t  ; do automatically add chapters
                         :book-chapter "Computer Science"
                         "~/Notes/cs"
                         :book-chapter "Mathematics"
                         "~/Notes/math"
                         :book-chapter "Emacs"
                         "~/Notes/emacs"
                         :book-end t ; the rest will not be placed in the book
                         "~/Notes"   ; so we can find the notes-anthology page
                         "~/Notes/private"
                         :force-publish ("index")
                         :default "index")
              (:base "book-pdf"
                     :include "/notes-anthology[^/]*$"
                     :path "~/public_html/notes")
              ;; other publishing styles for each directory go here,
              ;; if desired
              )))

   In this example, there would be a file called
`~/Notes/notes-anthology.muse', which would contain just the following.
The resulting book would be published to
`~/public_html/notes/notes-anthology.pdf'.

     #title My Technology Ramblings

   Another way is to call the `muse-book-publish-project' function
manually, with a custom project entry.  An example of this may be found
in John Wiegley's configuration file at `examples/johnw/muse-init.el',
in the `muse-publish-my-books' function.

Styles provided
---------------

`book-latex'
     Publish a book in LaTeX form.  The header and footer are different
     than the normal LaTeX publishing mode.

     Header for publishing a presentation (slides) using ConTeXt.

     Any of the predefined modules, which are available in the
     tex/context/base directory, can be used by writing a "module"
     directive at the top of the Muse file; if no such directive is
     provided, module pre-01 is used.  Alternatively, you can use your

     contents.

     Most of the time, it is best to have a table of contents on the
     first page, with a new page immediately following.  To make this
     work with documents published in both HTML and ConTeXt, we need to
     ignore the <contents> tag.

     If you don't agree with this, then set this option to non-nil, and
     it will do what you expect.

9.6 Integrating with ikiwiki
============================

Note: Support for Ikiwiki is not yet complete.  Use at your own risk.

   Ikiwiki is a wiki compiler (`http://ikiwiki.info/').  Emacs Muse can
(not yet) be used as a source format for Ikiwiki pages with the plugin
`IkiWiki::Plugin::muse'.

   The `lisp/muse-ikiwiki.el' file provides publishing functions and
styles for Ikiwiki.  The plugin for Ikiwiki to recognize Muse files is
provided by the `contrib/ikiwiki/IkiWiki/Plugin/muse.pm' file.  Two
sample init files are available in the `examples/ikiwiki' directory.
Configure your `ikiwiki.setup' file so that the `muse_init' variable
has the location of your Muse init file.

   If you are using CGI, The directory `contrib/ikiwiki/IkiWiki' must
be copied to the same directory as the CGI script that Ikiwiki
generates.  When publishing your wiki, the PERL5LIB environment
variable must contain the path to the `contrib/ikiwiki/IkiWiki'
directory.

Styles provided
---------------

`ikiwiki'
     Supports publishing XHTML output that Ikiwiki can understand.


Options provided
----------------

`muse-ikiwiki-header'
     Header used for publishing Ikiwiki output files.

     This may be text or a filename.

`muse-ikiwiki-footer'
     Footer used for publishing Ikiwiki output files.

     This may be text or a filename.


Other relevant options
----------------------

`muse-colors-evaluate-lisp-tags'
     Specify whether to evaluate the contents of <lisp> tags at display
     time.  If nil, don't evaluate them.  If non-nil, evaluate them.

     The actual contents of the buffer are not changed, only the
     displayed text.

`muse-html-src-allowed-modes'
     Modes that we allow the <src> tag to colorize.  If `t', permit the
     <src> tag to colorize any mode.

     If a list of mode names, such as `'("html" "latex")', and the lang
     argument to <src> is not in the list, then use fundamental mode
     instead.

`muse-publish-enable-dangerous-tags'
     If non-nil, publish tags like <lisp> and <command> that can call
     external programs or expose sensitive information.  Otherwise,
     ignore tags like this.

     This is useful to set to `nil' when the file to publish is coming
     from an untrusted source.

File: muse.info,  Node: Journal,  Next: LaTeX,  Prev: Ikiwiki,  Up: Publishing Styles

9.7 Keeping a journal or blog
=============================

The module facilitates the keeping and publication of a journal.  When
publishing to HTML, it assumes the form of a web log, or blog.

   The input format for each entry is as follows.

     * 20040317: Title of entry

     text for the entry.

     <qotd>
     "You know who you are. It comes down to a simple gut check: You
     either love what you do or you don't. Period." -- P. Bronson
     </qotd>

   The "qotd", or Quote of the Day, is entirely optional.  When
generated to HTML, this entry is rendered as the following.

     <div class="entry">
       <div class="entry-qotd">
         <h3>Quote of the Day:</h3>
         <p>"You know who you are. It comes down to a simple gut
           check: You either love what you do or you don't. Period."
           -- P. Bronson</p>
       </div>
       <div class="entry-body">
         <div class="entry-head">
           <div class="entry-date">
             <span class="date">March 17, 2004</span>
           </div>
           <div class="entry-title">
             <h2>Title of entry</h2>
           </div>
         </div>
         <div class="entry-text">
           <p>Text for the entry.</p>
         </div>
       </div>
     </div>

   The plurality of "div" tags makes it possible to display the entries
in any form you wish, using a CSS style.

   Also, an .RDF file can be generated from your journal by publishing
it with the "rdf" style.  It uses the first two sentences of the first
paragraph of each entry as its "description", and auto-generates tags
for linking to the various entries.

muse-project-alist considerations
---------------------------------

If you wish to publish an RDF or RSS feed, it is important to include
the `:base-url' attribute in your `muse-project-alist' entry for your
Journal projects.  An example follows.

     (setq muse-project-alist
           '(("Journal" ("~/Journal/"
                         :default "journal")
             (:base "journal-rss"
                    :base-url "http://example.org/journal/"

9.9 Publish a poem to LaTeX or PDF
==================================

The `muse-poem' module makes it easy to attractively publish and
reference poems in the following format, using the "memoir" module for
LaTeX publishing.  It will also markup poems for every other output
style, though none are nearly as pretty.

     Title


     Body of poem


     Annotations, history, notes, etc.

   Once a poem is written in this format, just publish it to PDF using
the `poem-pdf' style.  To make an inlined reference to a poem that
you've written - for example, from a blog page - there is a "poem" tag
defined by this module.

     <poem title="name.of.poem.page">

   Let's assume the template above was called `name.of.poem.page'; then
the above tag would result in this inclusion.

     ** Title

     > Body of poem

   John Wiegley uses this module for publishing all of the poems on his
website, which are at `http://www.newartisans.com/johnw/poems.html'.

10.1 Specifying functions to mark up text
=========================================

`muse-publish-markup-functions'

   An alist of style types to custom functions for that kind of text.

   This is used by publishing styles to attempt to minimize the amount
of custom regexps that each has to define.  `muse-publish' provides
rules for the most common types of markup.

   Each member of the list is of the following form.

     (SYMBOL FUNCTION)

   * SYMBOL Describes the type of text to associate with this rule.
     `muse-publish-markup-regexps' maps regexps to these symbols.

   * FUNCTION Function to use to mark up this kind of rule if no
     suitable function is found through the `:functions' tag of the
     current style.

10.2 Markup rules for publishing
================================

`muse-publish-markup-regexps'

   List of markup rules for publishing a page with Muse.

   The rules given in this variable are invoked first, followed by
whatever rules are specified by the current style.

   Each member of the list is either a function, or a list of the
following form.

     (REGEXP/SYMBOL TEXT-BEGIN-GROUP REPLACEMENT-TEXT/FUNCTION/SYMBOL)

   * REGEXP A regular expression, or symbol whose value is a regular
     expression, which is searched for using `re-search-forward'.

   * TEXT-BEGIN-GROUP The matching group within that regexp which
     denotes the beginning of the actual text to be marked up.

   * REPLACEMENT-TEXT A string that will be passed to `replace-match'.

     If it is not a string, but a function, it will be called to
     determine what the replacement text should be (it must return a
     string).  If it is a symbol, the value of that symbol should be a
     string.

   The replacements are done in order, one rule at a time.  Writing the
regular expressions can be a tricky business.  Note that case is never
ignored.  `case-fold-search' is always bound to nil while processing
the markup rules.

Publishing order
----------------

This is the order that the publishing rules are consulted, by default.
This may be changed by customizing `muse-publish-markup-regexps'.

`trailing and leading whitespace'
     Remove trailing and leading whitespace from a file.

     This function is responsible for marking up emphasis and escaping
     some specials.

10.4 Tag specifications for special markup
==========================================

`muse-publish-markup-tags'

   A list of tag specifications, for specially marking up text.

   XML-style tags are the best way to add custom markup to Muse.  This
is easily accomplished by customizing this list of markup tags.

   For each entry, the name of the tag is given, whether it expects a
closing tag and/or an optional set of attributes, whether it is
nestable, and a function that performs whatever action is desired within
the delimited region.

   The tags themselves are deleted during publishing, before the
function is called.  The function is called with three arguments, the
beginning and end of the region surrounded by the tags.  If properties
are allowed, they are passed as a third argument in the form of an
alist.  The `end' argument to the function is always a marker.

   Point is always at the beginning of the region within the tags, when
the function is called.  Wherever point is when the function finishes is
where tag markup will resume.

   These tag rules are processed once at the beginning of markup, and
once at the end, to catch any tags which may have been inserted
in-between.

10.5 Parameters used for defining styles
========================================

Style elements are tags that define a style.  Use either
`muse-define-style' or `muse-derive-style' (*note Deriving Styles::) to
create a new style.

 -- Function: muse-define-style name &rest elements

Usable elements
---------------

`:suffix'
     File extension to use for publishing files with this style.

`:link-suffix'
     File extension to use for publishing links to Muse files with this
     style.

`:osuffix'
     File extension to use for publishing second-stage files with this
     style.

     For example, PDF publishing generates a LaTeX file first, then a
     PDF from that LaTeX file.

`:regexps'
     List of markup rules for publishing a page with Muse.  *Note
     muse-publish-markup-regexps::.

`:functions'
     An alist of style types to custom functions for that kind of text.
     *Note muse-publish-markup-functions::.

`:strings'
     Strings used for marking up text with this style.

     These cover the most basic kinds of markup, the handling of which
     differs little between the various styles.

`:tags'
     A list of tag specifications, used for handling extra tags.  *Note
     muse-publish-markup-tags::.

`:specials'
     A table of characters which must be represented specially.

`:before'
     A function that is to be executed on the newly-created publishing
     buffer (or the current region) before any publishing occurs.

     This is used to set extra parameters that direct the publishing
     process.

`:before-end'
     A function that is to be executed on the publishing buffer (or the
     current region) immediately after applying all of the markup
     regexps.

     This is used to fix the order of table elements (header, footer,
     body) in XML-ish styles.

`:after'
     A function that is to be executed on the publishing buffer after
     :before-end, and immediately after inserting the header and footer.

     This is used for generating the table of contents as well as
     setting the file coding system.

`:final'
     A function that is to be executed after saving the published file,
     but while still in its buffer.

     This is used for generating second-stage documents like PDF files
     from just-published LaTeX files.

     The function must accept three arguments: the name of the muse
     source file, the name of the just-published file, and the name of
     the second-stage target file.  The name of the second-stage target
     file is the same as that of the just-published file if no
     second-stage publishing is required.

`:header'
     Header used for publishing files of this style.

     This may be a variable, text, or a filename.  It is inserted at the
     beginning of a file, after evaluating the publishing markup.

`:footer'
     Footer used for publishing files of this style.

     This may be a variable, text, or a filename.  It is inserted at
     the end of a file, after evaluating the publishing markup.

`:style-sheet'
     Style sheet used for publishing files of this style.

     This may be a variable or text.  It is used in the header of HTML
     and XHTML based publishing styles.

`:browser'
     The function used to browse the published result of files of this
     style.

File: muse.info,  Node: Deriving Styles,  Prev: Style Elements,  Up: Extending Muse

10.6 Deriving a new style from an existing one
==============================================

To create a new style from an existing one, use `muse-derive-style' as
follows.  This is a good way to fix something you don't like about a
particular publishing style, or to personalize it.

 -- Function: muse-derive-style new-name base-name &rest elements

   The derived name is a string defining the new style, such as
"my-html".  The base name must identify an existing style, such as
"html" - if you have loaded `muse-html'.  The style parameters are the
same as those used to create a style, except that they override whatever
definitions exist in the base style.  However, some definitions only
partially override.  The following parameters support partial
overriding.

   *Note Style Elements::, for a complete list of all parameters.

`:functions'
     If a markup function is not found in the derived style's function
     list, the base style's function list will be queried.

`:regexps'
     All regexps in the current style and the base style(s) will be
     used.

`:strings'
     If a markup string is not found in the derived style's string
     list, the base style's string list will be queried.

* Muse List Edit Minor Mode::   Edit lists easily in other major modes.

\1f
File: muse.info,  Node: Muse List Edit Minor Mode,  Up: Miscellaneous

11.1 Edit lists easily in other major modes
===========================================

`muse-list-edit-minor-mode' is meant to be used with other major modes,
such as Message (for composing email) and debian-changelog-mode (for
editing debian/changelog files).

   It implements practically perfect support for editing and filling
lists.  It can even handle nested lists.  In addition to Muse-specific
list items ("-", numbers, definition lists, footnotes), it can also
handle items that begin with "*" or "+".  Filling list items behaves in
the same way that it does in Muse, regardless of whether filladapt is
also enabled, which is the primary reason to use this tool.

Installation
------------

To use it, add "(require 'muse-mode)" to your Emacs customization file
and add the function `turn-on-muse-list-edit-minor-mode' to any mode
hooks where you wish to enable this minor mode.

Keybindings

`muse-list-edit-minor-mode' uses the following keybindings.

`M-RET (`muse-l-e-m-m-insert-list-item')'
     Insert a new list item at point, using the indentation level of the
     current list item.

`C-< (`muse-l-e-m-m-decrease-list-item-indent')'
     Decrease indentation of the current list item.

`C-> (`muse-l-e-m-m-increase-list-item-indent')'
     Increase indentation of the current list item.


Functions
---------

 -- Function: muse-list-edit-minor-mode
     This is a global minor mode for editing files with lists.  It is
     meant to be used with other major modes, and not with Muse mode.

     Interactively, with no prefix argument, toggle the mode.  With
     universal prefix ARG turn mode on.  With zero or negative ARG turn
     mode off.

     This minor mode provides the Muse keybindings for editing lists,
     and support for filling lists properly.

     It recognizes not only Muse-style lists, which use the "-"
     character or numbers, but also lists that use asterisks or plus
     signs.  This should make the minor mode generally useful.

     Definition lists and footnotes are also recognized.

     Note that list items may omit leading spaces, for compatibility
     with modes that set `left-margin', such as `debian-changelog-mode'.

 -- Function: turn-on-muse-list-edit-minor-mode
     Unconditionally turn on Muse list edit minor mode.

 -- Function: turn-off-muse-list-edit-minor-mode
     Unconditionally turn off Muse list edit minor mode.

13 History of This Document
***************************

   * 2004 John Wiegley started Muse upon realizing that EmacsWiki had
     some serious limitations. Around February 2004, he started making
     "emacs-wiki version 3.00 APLHA", which eventually became known as
     Muse.

     Most of those who frequent the emacs-wiki mailing list continued
     to use emacs-wiki, mainly because Planner hasn't been ported over
     to it.

     As of 2004-12-01, Michael Olson became the maintainer of Muse, as
     per John Wiegley's request.

   * 2005 Michael Olson overhauled this document and added many new
     sections in preparation for the first release of Muse (3.01).

Appendix A GNU Free Documentation License
*****************************************

                      Version 1.2, November 2002

     Copyright (C) 2000,2001,2002  Free Software Foundation, Inc.
     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA

     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.

     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 for under this License.  Any other
     attempt to copy, modify, sublicense or distribute the Document is
     void, and will automatically terminate your rights under this
     License.  However, parties who have received copies, or rights,
     from you under this License will not have their licenses
     terminated so long as such parties remain in full compliance.

 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
     http://www.gnu.org/copyleft/.

     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.


ADDENDUM: How to use this License for your documents

   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.
