[description]
[para]

This document specifies both names and syntax of all the commands
which together are the doctoc markup language, version 1.

As this document is intended to be a reference the commands are listed
in alphabetical order, and the descriptions are relatively short.

A beginner should read the much more informally written
[term {doctoc language introduction}] first.


[section Commands]
[list_begin definitions]


[call [cmd comment] [arg plaintext]]

Toc markup. The argument text is marked up as a comment standing
outside of the actual text of the document. Main use is in free-form
text.

[call [cmd division_end]]

Toc structure. This command closes the division opened by the last
[cmd division_begin] command coming before it, and not yet closed.

[call [cmd division_start] [arg text] [opt [arg symfile]]]

Toc structure. This command opens a division in the table of
contents. Its counterpart is [cmd division_end]. Together they allow a
user to give a table of contents additional structure.

[para]

The title of the new division is provided by the argument [arg text].

[para]

If the symbolic filename [arg symfile] is present then the section
title should link to the referenced document, if links are supported
by the output format.

[call [cmd include] [arg filename]]

Templating. The contents of the named file are interpreted as text
written in the doctoc markup and processed in the place of the
include command. The markup in the file has to be self-contained. It
is not possible for a markup command to cross the file boundaries.

[call [cmd item] [arg file] [arg text] [arg desc]]

Toc structure. This command adds an individual element to the table of
contents. Each such element refers to a document. The document is
specified through the symbolic name [arg file]. The [arg text]
argument is used to label the reference, whereas the [arg desc]
provides a short descriptive text of that document.

[para]

The symbolic names are used to preserve the convertibility of this
format to any output format. The actual name of the file will be
inserted by the chosen formatting engine when converting the
input. This will be based on a mapping from symbolic to actual names
given to the engine.

[call [cmd lb]]

Text. The command is replaced with a left bracket. Use in free-form
text. Required to avoid interpretation of a left bracket as the start
of a markup command. Its usage is restricted to the arguments of other
markup commands.

[call [cmd rb]]

Text. The command is replaced with a right bracket. Use in free-form
text. Required to avoid interpretation of a right bracket as the end
of a markup command. Its usage is restricted to the arguments of other
commands.

[call [cmd toc_begin] [arg text] [arg title]]

Document structure. The command to start a table of contents. The
arguments are a label for the whole group of documents the index
refers to ([arg text]) and the overall title text for the index
([arg title]), without markup.

[para]

The label often is the name of the package (or extension) the
documents belong to.

[call [cmd toc_end]]

Document structure. Command to end a table of contents. Anything in
the document coming after this command is in error.

[call [cmd vset] [arg varname] [arg value] ]

Templating. In this form the command sets the named document variable
to the specified [arg value]. It does not generate output. I.e. the
command is replaced by the empty string.

[call [cmd vset] [arg varname]]

Templating. In this form the command is replaced by the value of the
named document variable

[list_end]
