+Provides core support for the Eclipse platform online
+help system.
+<h2>
+Package Specification</h2>
+There is a general mechanism (defined at the plug-in level) by which individual
+plug-ins contribute online help and context-sensitive help for their component.
+The help system UI is responsible for accessing this information and displaying
+it to the user.
+<p>The actual help system UI implementation is an optional piece that plugs
+in to the platform's standard <tt>org.eclipse.help.support</tt> extension
+point. At most one such help system UI should be contributed in any given
+configuration of the platform. In general terms, implementing a help system
+UI involves:
+<ul>
+<li>
+Implementing the <tt>IHelp</tt> interface to display help to the user.</li>
+
+<li>
+Declaring an extension of the <tt>org.eclipse.help.support</tt> extension
+point that mentions the name of that class.</li>
+
+<li>
+Ensuring that the platform is not configured with any other plug-ins which
+contribute to the <tt>org.eclipse.help.support</tt> extension point.</li>
+</ul>
+Note that the platform declares a plug-in (<tt>org.eclipse.help.workbench</tt>)
+which implements the help system UI. This plug-in would need to be omitted
+from the platform configuration when using a replacement.

+<p>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 identify the currently active context. The context definition
+with a matching id is then retrieved. This context element contains the
+brief description that is to be displayed to the user, as well as related
+topics that the user might find useful for understanding the current context.
+<br>&nbsp;
+<p><b><i>Examples:</i></b>
+<p>The following is an example of using the <tt>contexts</tt> extension
+point.
+<p>(in file <tt>plugin.xml</tt>)
+<p><tt>&nbsp;&nbsp; &lt;extension point="org.eclipse.help.contexts"></tt>
+<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;contexts name="xyzContexts.xml"/></tt>

+<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;context&nbsp; id="generalContextId"></tt>
+<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;description> This
+is a sample F1 help string.&lt;/description></tt>

+label="Help Related Topic 1"/></tt>
+<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;topic href="contexts/RelatedContext2.html"&nbsp;
+label="Help Related Topic 2"/></tt>
+<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/context></tt>
+<br><tt>&nbsp;&nbsp;&nbsp; &lt;/contexts></tt>
+<br>&nbsp;
+<p><b><i>API Information</i>: </b>No code is required to use this extension

+mentioned in the <tt>plugin.xml</tt> file.
+<p><b><i>Supplied Implementation: </i></b>The optional default implementation
+of the help system UI supplied with the Eclipse platform fully supports
+the <tt>contexts</tt> extension point.

+<p>In general, a plug-in that needs to provide online help will define
+its own topics manifests and the necessary actions manifests to wire the
+topics to the correct place. In the end, the help system is configured
+to be launched as some actions, and the id of the views manifest will be
+used to do so.
+<p>There are four types of XML elements a plug-in can use: the topic, the
+infoset, the actions, and the insert elements.
+<p><b>The topic element</b>
+<p>With respect to topics elements, all the topics are contributed as part
+of the topics container element. They can have a hierarchical structure,
+or can be listed as a flat list. A topics manifest is viewed as a data
+source for further topics interleaving and organization into an integrated
+web, with different view perspectives.&nbsp; In addition, topics can be
+acted upon by specifying their id's, but one can also act on a group of
+topics by specifying the id of the topics element that contains them.&nbsp;
+Later when wiring topics to views or other topics, the structure defined
+in the topics manifest is maintained (subject to alterations done by insert
+actions).
+<p>The topic element is the workhorse of the navigation structure. There
+are three typical uses for the topic element:
+<p>1.&nbsp; To provide a link to a documentation file - often an HTML file
+in some doc.zip.
+<br>2.&nbsp; To act as a container for other topics, either in the same
+manifest or another.
+<br>3.&nbsp; To provide an insertion point for other topics, either in
+the same manifest or another.
+<p><b><i>1.&nbsp; Topics as links</i></b>
+<br>The simplest use of a topic is as a link to a documentation file.
+<p><tt>&lt;topic label="Some concept file" href="concepts/some_file.html"
+/></tt>
+<p>The href attribute is relative to the plug-in that the manifest file
+belongs to.&nbsp; If you need to access a file in another plug-in, you
+can use the syntax
+<p><tt>&lt;topic label="topic in another plug-in" href="../other.plugin.id/concepts/some_other_file.html"
+/></tt>
+<p><b><i>2.&nbsp; Topics as containers</i></b>
+<br>The next most common use of a topic is to use it as a container for
+other topics.&nbsp; The container topic itself can always refer to a particular
+file as well.
+<p><tt>&lt;topic label="Integrated Development Environment" href="concepts/ciover.htm"
+></tt>
+<br><tt>&nbsp; &lt;topic label="Starting the IDE" href="concepts/blah.htm"
+/></tt>
+<br><tt>&nbsp; ...</tt>
+<br><tt>&lt;/topic></tt>
+<p>If you leave the label off the topic, it acts as a "pure" container,
+used either as an anchor for other topics to insert around, or to simplify
+inserting a group of topics into a specific point in the merged navigation.
+<p><b><i>3.&nbsp; Topics as insertion points</i></b>
+<br>Topics can be used as insertion points.&nbsp; They provide a logical
+place for other topics to try and merge around.&nbsp; To act as an insertion
+point, the topic must have an id attribute.
+<p><b>The infoset element</b>
+<p><font color="#000000">An information set is an entry point into a documentation
+web: a collection of all the online documentation that can be displayed
+by the help viewer when launched. It can be thought of as a collection
+of views.</font>
+<p><font color="#000000">Views are intended to provide high level semantic
+groupings within a documentation web. They are defined using the </font><tt>infoview
+</tt><font color="#000000">element
+defined within an infoset. A documentation team could use a view to produce
+getting started, tasks, and references sections (or other views the product
+team defines). The platform does not specify the actual sections, only
+the mechanism for defining them.</font>
+<p><font color="#000000">For example, there can be a "task view" defined
+which is a merge of all the topics from a "how to do something" perspective.
+Another view, a "component view", can also be defined which is a topics
+tree displaying all components and their documentation. In the current
+implementation of the help system a "search view" is always added to the
+list of views. This view enables the user to access help topics by querying
+for a word/phrase.</font>
+<p>The infoview element represents a container for topics that can be "shared"
+across plug-ins.&nbsp; It is a perspective on the entire documentation.
+There may be times when a number of different plug-ins contribute to the
+same logical documentation component.&nbsp; This element ensures that during
+a "component view," they are correctly merged together into a coherent
+view.
+<p><b>The actions element</b>
+<p>The actions manifest contains scripting actions to be performed on topics
+and views. Currently there is only one kind of action, the insert action,
+which is used to write topics and views together into one integrated information
+web, with multiple views.
+<p>The actions are structural actions (insert) and, thus, apply to a certain
+infoview. So, all the insert actions in a manifest build the topic hierarchy
+in one infoview.
+<p><b>The insert element</b>
+<p>One of the most complicated parts of a componentized navigation is how
+to create an integrated information structure with a continuous flow of
+navigation.&nbsp; To do this, we need a mechanism to publish insertion
+points, choose which insertion point we want to use, and to indicate where
+we want to insert topics (parent, child, before, after).
+<p>The insertion points can be topics or views.&nbsp; A topic indicates
+its willingness to be an insertion point by providing an id. Views are
+required to have id's.&nbsp; Only fully qualified ids are use as references.
+<font color="#000000">For
+example, the fully qualified topic id of the topic &lt;topic id="concepts"
+label="Concepts">&nbsp; in the org.eclipse.help.examples.ex1
+</font>plug-in<font color="#000000">
+is org.eclipse.help.examples.ex1.concepts.</font>
+<p>Since the insertion points are typically located in other plug-ins,
+and these plug-in may not be installed, one can specify an alternate insertion
+point. By default, if none of the choices succeed, the topic stays under
+its component hierarchy. The "to" attribute specifies the target insertion
+point. The topic specified by the "from" attribute is the topic being inserted.&nbsp;
+Followings are some possible ways to insert a topic and they are specified
+using the as attribute:
+<ul>
+<li>
+As a child of the insertion point, which is the most common.</li>
+
+<li>
+As the first child of the insertion point</li>
+
+<li>
+As the last child of the insertion point</li>
+
+<li>
+As the previous sibling of the insertion point (i.e., just before the insertion
+point at the same level in the navigation tree)</li>
+
+<li>
+As the next sibling of the insertion point (i.e., just after the insertion
+point at the same level in the navigation tree)</li>
+</ul>
+Alternative insertion options are provided, when previous ones could not
+be performed. The nested insert subelements of the insert element provide
+these alternatives. This can be thought of as a "fall-back" mechanism where
+if an insert action fails, the nested insert action will be executed. Once
+the first choice insertion point has been satisfied, the other alternative
+insertion points are ignored.

+
+<h4>
+Non-integrated components</h4>
+There is a variation in the default handling of contributions to allow
+for "non-integrated" components. Here is a simple scenario: an ISV creates
+a component that includes some documentation. The component can be installed
+by anybody using eclipse, including some larger products that have their
+own infosets. The ISV may or may not know in advance who are the potential
+users of his component. In that case, he wants to ensure that the documentation
+for the component can be accessed, no matter how the component is integrated.
+If there are well-known infosets in some products, the ISV can target its
+documentation for wiring into those infosets. In that case the default
+infoset provided by the component should not be shown. If there are no
+well-known infosets that the component can be wired into (because they
+have not been installed or they simply do not exist), then the component
+documentation should be shown in the default infoset provided with the
+component.
+<p>To support this non-integrated or loosely integrated documentation,
+a plugin can define an infoset and associated actions and set their <b>standalone</b>
+attribute to false. This has the effect of executing the inserts only when
+those topics have never been contributed anywhere else and only display
+the infoset if it is not empty. In other words, this behaves as: "if this
+is an independent plugin, and there are no topics contributed to some well-known
+infoset, then insert the documentation into a standalone info set". Empty
+standalone infosets are not shown. This really says that if the topics
+contributed by the plugin are inserted into well known infosets, then the
+standalone actions did not insert anything in the standalone infoset, so
+just ignore this empty infoset.
+<br>Setting standalone attributes on actions and infosets is useful when
+providing a "Catch all" scenario, when documentation cannot be contributed
+to a well-known infoset but the plugin documentation should still appear
+somewhere.
+<br>&nbsp;
+<p><b><i>API Information</i>:<font color="#CC0000"> </font></b>No code
+is required to use this extension point. All that is needed is to supply
+the appropriate manifest files mentioned in the <tt>plugin.xml</tt> file.
+<p><i><b>Supplied Implementation:</b> </i>The optional default implementation
+of the help system UI supplied with the Eclipse platform fully supports
+the <tt>contributions</tt> extension point.

+<b><i>Identifier: </i></b>org.eclipse.help.support

+<b><i>Examples:</i></b>
+<p>The following is a sample usage of the <tt>support</tt> extension point:

+<p><i><b>Supplied Implementation:</b> </i>The <tt>org.eclipse.help.workbench</tt>
+plug-in contains an implementation of the help system UI. Although this
+plug-in is supplied with the Eclipse platform, it is entirely optional
+and can be safely omitted from the platform configuration.
