+ lv2:documentation """
+<p>This extension defines an interface that can be used in LV2 plugins and
+hosts to create UIs for plugins. The UIs are similar to plugins and reside in
+shared object files in an LV2 bundle. UIs are associated with a plugin in RDF
+using the triples:</p>
+
+<pre class="turtle-code">
+@prefix ui: &lt;http://lv2plug.in/ns/extensions/ui#&gt; .
+
+&lt;http://my.plugin&gt; ui:ui &lt;http://my.pluginui&gt; .
+&lt;http://my.pluginui&gt; a ui:GtkUI ;
+ ui:binary &lt;myui.so&gt; .
+</pre>
+
+<p>where &lt;http://my.plugin&gt; is the URI of the plugin,
+&lt;http://my.pluginui&gt; is the URI of the plugin UI and &lt;myui.so&gt; is
+the relative URI to the shared object file.</p>
+
+<p>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. A UI MUST specify its class in
+the RDF data (ui:GtkUI in the above example). The class defines what type the
+UI is, e.g. what graphics toolkit it uses. Any type of UI class can be defined
+separately from this extension.</p>
+
+<p>It is 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.</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 are not necessarily the same process (and not even
+necessarily on the same machine). This means that plugin and UI code 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 this header is the only method of communication
+between UIs and plugin instances (extensions may define more, though this is
+discouraged unless absolutely necessary since the significant benefits of
+network transparency and serialisability are lost).</p>
+
+<p>Since the LV2 specification itself allows for extensions that may add new
+functionality that could be useful to control with a UI, this extension allows
+for meta-extensions that can extend the interface between the UI and the
+host. These extensions mirror the extensions used for plugins - there are
+required and optional "features" that you declare in the RDF data for the
+UI:</p>
+
+<pre class="turtle-code">
+&lt;http://my.pluginui&gt; lv2:requiredFeature &lt;http://my.feature&gt; .
+&lt;http://my.pluginui&gt; lv2:optionalFeature &lt;http://my.feature&gt; .
+</pre>
+
+<p>The rules for a UI with a required or optional feature are identical to
+those of lv2:Plugin instances: if a UI declares a feature as required, the host
+is NOT allowed to load it unless it supports that feature; and if it does
+support a feature, it MUST pass an appropriate LV2_Feature struct to the UI's
+instantiate() method. These features may be used to specify how to pass
+specific types of data between the UI and the plugin port buffers (see
+LV2UI_Write_Function for details).</p>
+
+<p>UIs written to this specification do not need to be threadsafe - the
+functions defined below may only be called in the same thread the UI main loop
+is running in.</p>
+
+<p>Note that this UI extension is NOT a lv2:Feature. There is no way for a
+plugin to know whether the host that loads it supports UIs or not, and the
+plugin must always work without the UI (although it may be rather useless
+unless it has been configured using the UI in a previous session). From the
+plugin perspective, control from a UI is the same as control from anywhere else
+(e.g. the host, the user): via ports.</p>
+
+<p>A UI does not have to be a graphical widget, it could just as well be a
+server listening for OSC input or an interface to some sort of hardware device,
+depending on the RDF class of the UI.</p>

+<p>This extension defines a number of units for use in audio processing.</p>

+<p>For example, to say that a gain port's value is in decibels (units:db)</p>

+ lv2:name "gain" ;
+ units:unit units:db

+</pre>
+
+<p>Using the same form, plugins may also specify one-off units inline, to give
+better display hints to hosts:</p>

+ units:symbol "fr" ;
+ units:render "%f f"
+ ]
+] .
+</pre>
+
+<p>It is also possible to define conversions between various units, which makes
+it possible for hosts to automatically and generically convert from a given
+unit to a desired unit. The units defined in this extension include conversion
+definitions where it makes sense to do so.</p>
