         For registering an online help contribution for an individual plug-in.

&lt;p&gt;Each plug-in that contributes help files should in general do the following:
&lt;ul&gt;
&lt;ul&gt;
&lt;li&gt;
author the html files, zip html files into doc.zip, and store the zip file
in the plug-in directory.&lt;/li&gt;

&lt;li&gt;
create TOC files that describe Table of Contents for the help and the necessary
topic interleaving. See the syntax below.&lt;/li&gt;

&lt;li&gt;
the plugin.xml file should extend the &lt;tt&gt;org.eclipse.help.toc&lt;/tt&gt; extension
point and specify TOC file(s).&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;p&gt;Optionally, a search index can be prebuilt and registered using &lt;code&gt;index&lt;/code&gt; element in order to performance of the first search attempt. Only one index per plug-in can be registered - multiple &lt;code&gt;index&lt;/code&gt; elements will result in undefined behaviour.

&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;!ATTLIST link toc CDATA #REQUIRED &gt;&lt;/tt&gt;
&lt;p&gt;In general, a plug-in that needs to provide online help will define
its own TOC files. In the end, the help system is configured to be launched
as some actions, and the path of the TOC file can be used to do so.
&lt;p&gt;&lt;b&gt;The topic element&lt;/b&gt;
&lt;p&gt;All help topic element are contributed as part of the toc container
element. They can have a hierarchical structure, or can be listed as a
flat list.
&lt;p&gt;The topic element is the workhorse of structure of Table of Contents.
There are two typical uses for the topic element:
&lt;p&gt;1.&amp;nbsp; To provide a link to a documentation file - usually an HTML
file.
&lt;br&gt;2.&amp;nbsp; To act as a container for other toc, either in the same manifest
or another.
&lt;p&gt;&lt;b&gt;&lt;i&gt;1.&amp;nbsp; Topics as links&lt;/i&gt;&lt;/b&gt;
&lt;br&gt;The simplest use of a topic is as a link to a documentation file.
&lt;p&gt;&lt;tt&gt;&amp;lt;topic label=&quot;Some concept file&quot; href=&quot;concepts/some_file.html&quot;
/&gt;&lt;/tt&gt;
&lt;p&gt;The href attribute is relative to the plug-in that the manifest file
belongs to.&amp;nbsp; If you need to access a file in another plug-in, you
can use the syntax
&lt;p&gt;&lt;tt&gt;&amp;lt;topic label=&quot;topic in another plug-in&quot; href=&quot;../other.plugin.id/concepts/some_other_file.html&quot;
/&gt;&lt;/tt&gt;
&lt;p&gt;&lt;b&gt;&lt;i&gt;2.&amp;nbsp; Topics as containers&lt;/i&gt;&lt;/b&gt;
&lt;br&gt;The next most common use of a topic is to use it as a container for
other toc.&amp;nbsp; The container topic itself can always refer to a particular
file as well.
&lt;p&gt;&lt;tt&gt;&amp;lt;topic label=&quot;Integrated Development Environment&quot; href=&quot;concepts/ciover.htm&quot;
&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; &amp;lt;topic label=&quot;Starting the IDE&quot; href=&quot;concepts/blah.htm&quot;
/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; ...&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;lt;/topic&gt;&lt;/tt&gt;
&lt;p&gt;&lt;b&gt;The link element&lt;/b&gt;
&lt;p&gt;The link element allows to link Table of Contents defined in another
toc file.&amp;nbsp; All the topics from the toc file specified in the toc attribute
will appear in the table of contents as if they were defined directly in
place of the link element.&amp;nbsp; To include toc from api.xml file you could
write
&lt;p&gt;&lt;tt&gt;&amp;lt;topic label=&quot;References&quot; &gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; ...&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; &amp;lt;link toc=&quot;api.xml&quot; /&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; ...&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;lt;/topic&gt;&lt;/tt&gt;
&lt;p&gt;&lt;b&gt;The anchor element&lt;/b&gt;
&lt;p&gt;The anchor element defines a point that will allow linking other toc
files to this navigation, and extending it, without using the link element
and referencing other toc files from here.&amp;nbsp; To allow inserting Table
of Contents with more topics after the &quot;ZZZ&quot; document you would define
an anchor as follows:
&lt;p&gt;&lt;tt&gt;...&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;lt;topic label=&quot;zzz&quot; href=&quot;zzz.html&quot; /&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;lt;anchor id=&quot;moreapi&quot; /&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;...&lt;/tt&gt;
&lt;p&gt;&lt;b&gt;The toc element&lt;/b&gt;
&lt;p&gt;The toc element is a Table of Contents that groups topics and other
elements defined in this file.&amp;nbsp; The label identifies the table of
contents to the user, when it is displayed to the user.&amp;nbsp; The optional topic
attribute is the path to a topic file describing the TOC.&amp;nbsp; The optional
link_to attribute allows for linking toc from this file into another toc
file being higher in the navigation hierarchy.&amp;nbsp; The value of the link_to
attribute must specify an anchor in another toc file. To link toc from
myapi.xml to api.xml file, specified in another plugin you would use
the syntax
&lt;p&gt;&lt;tt&gt;&amp;lt;toc link_to=&quot;../anotherPlugin/api.xml#moreapi&quot; label=&quot;My Tool
API&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;...&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;lt;toc /&gt;&lt;/tt&gt;
&lt;p&gt;where # character separates toc file name from the anchor identifier.
&lt;/p&gt;

&lt;br&gt;&lt;tt&gt;&amp;lt;/toc&gt;&lt;/tt&gt;&lt;/blockquote&gt;

&lt;p&gt;&lt;br&gt;(in file &lt;tt&gt;tasks.xml&lt;/tt&gt;)
&lt;blockquote&gt;&lt;tt&gt;&amp;lt;toc label=&quot;Building a Project&quot;&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;lt;topic label=&quot;Building a Project&quot; href=&quot;build/building.html&quot;&gt;&lt;/tt&gt;

&lt;br&gt;&lt;tt&gt;&amp;lt;/toc&gt;&lt;/tt&gt;&lt;/blockquote&gt;

&lt;p&gt;&lt;br&gt;(in file &lt;tt&gt;samples.xml&lt;/tt&gt;)
&lt;blockquote&gt;&lt;tt&gt;&amp;lt;toc link_to=&quot;maindocs.xml#samples&quot; label=&quot;Using The
Compile Tool&quot;&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;lt;topic label=&quot;The Compile Tool Sample&quot; href=&quot;compilesample/example.html&quot;&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; &amp;lt;topic label=&quot;Step 1&quot; href=&quot;compilesample/step1.html&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; &amp;lt;topic label=&quot;Step 2&quot; href=&quot;compilesample/step2.html&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; &amp;lt;topic label=&quot;Step 3&quot; href=&quot;compilesample/step3.html&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp; &amp;lt;topic label=&quot;Step 4&quot; href=&quot;compilesample/step4.html&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;lt;/topic&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;lt;/toc&gt;&lt;/tt&gt;&lt;/blockquote&gt;


&lt;p&gt;Assuming more documents exists with the path starting with &quot;samples&quot;,
they will not be displayed in the navigation tree, but be accessible using
search.&amp;nbsp; It is due to the presence of &quot;extradir&quot; attribute in the
element &lt;tt&gt;&amp;lt;toc file=&quot;sample.xml&quot; extradir=&quot;samples&quot; /&gt; &lt;/tt&gt;inside&lt;tt&gt;
plugin.xml &lt;/tt&gt;file. For example searching for &quot;Creating Java Project&quot;
could return a document &quot;Other Ways of Creating Java Project&quot;, which path
is &lt;tt&gt;samples/sample2.html.&lt;/tt&gt;

&lt;p&gt;
&lt;b&gt;&lt;em&gt;Internationalization&lt;/em&gt;&lt;/b&gt;
The TOC XML files can be translated and the resulting copy (with translated
labels) should be placed in nl/&amp;lt;language&gt;/&amp;lt;country&gt; or nl/&amp;lt;language&gt;
directory.&amp;nbsp; The &amp;lt;language&gt; and &amp;lt;country&gt; stand for two letter
language and country codes as used in locale codes.&amp;nbsp; For example,
Traditional Chinese translations should be placed in the nl/zh/TW directory.&amp;nbsp;
The nl/&amp;lt;language&gt;/&amp;lt;country&gt; directory has a higher priority than
nl/&amp;lt;language&gt;.&amp;nbsp; Only if no file is found in the nl/&amp;lt;language&gt;/&amp;lt;country&gt;,
the file residing in nl/&amp;lt;language&gt; will be used.&amp;nbsp; The the root
directory of a plugin will be searched last.
&lt;p&gt;The documentation contained in doc.zip can be localized by creating
a doc.zip file with translated version of documents, and placing doc.zip
in
&lt;br&gt;nl/&amp;lt;language&gt;/&amp;lt;country&gt; or nl/&amp;lt;language&gt; directory. The help
system will look for the files under this directories before defaulting
to plugin directory.
