-<p>This extension defines an interface that can be used to create UIs for 
-plugins. The UIs are code that reside in shared object files in an LV2
-bundle and are referenced in the RDF data using the triples:</p>
-<pre class="turtle-code">
-@prefix pui:     &lt;http://lv2plug.in/ns/ext/pui#&gt; .
-&lt;http://example.org/my-ui&gt;  a             pui:Gtk2UI ;
-                            lv2:appliesTo &lt;http://example.org/my-plugin&gt; ;
-                            pui:binary     &lt;my-ui.so&gt; .
-</pre>
-<p>... where <code>http://example.org/my-plugin</code> is the URI of the plugin,
-<code>http://example.org/my-ui</code> is the URI of the plugin UI and
-<code>my-ui.so</code> is the relative URI to the shared object file. While it
-is possible to have the plugin UI and the plugin in the same shared object file
-it is probably a good idea to keep them separate so that hosts that don't want
-UIs don't have to load the UI code.</p>
-
-<p>A UI MUST specify its class in the RDF data and the class MUST be a proper
-subclass of pui:UI, in this case pui:Gtk2UI. The class defines what type the
-UI is, e.g. what graphics toolkit it uses. There are no UI classes defined in
-this extension, those are specified separately (and anyone can define their
-own).</p>
-
-<p>It's entirely possible to have multiple UIs for the same plugin, or to have
-the UI for a plugin in a different bundle from the actual plugin - this way
-people other than the plugin author can write plugin UIs independently without
-editing the original plugin bundle. It is also possible to have one UI that
-works with several different plugins.</p>
-
-<p>UIs should also be written in such a way that the host may load several
-instances of an UI, or different UIs, and use them with the same plugin
-instance.</p>
-
-<p>Note that the process that loads the shared object file containing the UI
-code and the process that loads the shared object file containing the actual
-plugin implementation do not have to be the same. There are many valid reasons
-for having the plugin and the UI in different processes, or even on different
-machines. This means that you can <strong>not</strong> use singletons and
-global variables and expect them to refer to the same objects in the UI and the
-actual plugin. The function callback interface defined in the header pui.h is
-all you can expect to work.</p>

-<p>The class which represents an LV2 plugin UI.
-</p>
-
-<p>To be used by a host a UI MUST have at least the following properties:</p>
-<ul>
-<li>rdf:type (with object a proper subclass of pui:UI)</li>
-<li>doap:name (one without language tag)</li>
-<li>lv2:binary (with a shared object file as object)</li>
-<li>lv2:appliesTo (with a LV2 plugin as object)</li>
-</ul>
-
-<p>The rdf:type of an UI is used by the host to decide whether it supports the
-UI and how to handle the LV2_PUI_Widget object that is returned by the UIs
-get_widget() function. For example, a type of pui:Gtk2UI might tell the
-host that LV2_PUI_Widget is a pointer to an object of a type defined in the
-Gtk+ library. No UI types are defined in this extension, that is intentionally
-left for other extensions.</p>
-
-<p>The doap:name property should be at most a few words in length using title
-capitalization, e.g. "Flashy Mixer GUI". Use lv2:documentation for more
-detailed descriptions.</p>
-
-<p>UIs may have optional or required features, specified using lv2:optionalFeature
-or lv2:requiredFeature. The same rules apply here as for plugins; a host MUST
-pass the LV2_Feature objects for all features it supports to the UI's
