&lt;p&gt;The contexts manifest files provide all the information needed when
context-sensitive help is requested by the user. The id is passed by the
platform to the help system to identify the currently active context.The context definitions with matching IDs are then retrieved. If a title is defined it will be used when context help is displayed in the Help view, both as the title in the related topics section and also as
the search term in the &quot;More results&quot; section. The IDs in the manifest file, must not contain the period character, since the IDs are uniquely identified by pluginID.contextID string when in memory.  The IContext object is then created by help system that contains descriptions and topics from all context definitions for a given ID in a plug-in.&amp;nbsp; The description is to be displayed to the user, and
related topics might be useful to the user for understanding the current
context.&amp;nbsp; The related topic are html files packaged in doc.zip, together
with topics that are part of on line help.

         The following is an example of using the contexts 
extension point: 
&lt;br&gt;
(in file &lt;tt&gt;plugin.xml&lt;/tt&gt;)
&lt;p&gt;
&lt;pre&gt;
   &lt;extension point=&quot;org.eclipse.help.contexts&quot;&gt; 
      &lt;contexts file=&quot;xyzContexts.xml&quot;/&gt; 
   &lt;/extension&gt; 
&lt;/pre&gt;
&lt;/p&gt;

&lt;p&gt;(in file &lt;tt&gt;xyzContexts.xml&lt;/tt&gt;)
&lt;p&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;contexts&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;context&amp;nbsp; id=&quot;generalContextId&quot;&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;description&gt; This
is a sample F1 help string.&amp;lt;/description&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;topic href=&quot;contexts/RelatedContext1.html&quot;&amp;nbsp;
label=&quot;Help Related Topic 1&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;topic href=&quot;contexts/RelatedContext2.html&quot;&amp;nbsp;
label=&quot;Help Related Topic 2&quot;/&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;/context&gt;&lt;/tt&gt;
&lt;br&gt;&lt;tt&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;lt;/contexts&gt;&lt;/tt&gt;
&lt;br&gt;&amp;nbsp;
&lt;/p&gt;

&lt;b&gt;&lt;em&gt;Externalizing Strings&lt;/em&gt;&lt;/b&gt;
The Context XML files can be translated and the resulting copy (with translated
descriptions 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 related topics 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.
