+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
+
+ @prefix pui: <http://lv2plug.in/ns/ext/pui#> .
+ @prefix pui-gtk: <http://lv2plug.in/ns/ext/pui-gtk#> .
+ <http://example.org/my-ui> a pui-gtk:GtkUI ;
+ lv2:appliesTo <http://example.org/my-plugin> ;
+ pui:binary <my-ui.so> .
+
+where http://example.org/my-plugin
is the URI of the plugin,
+http://example.org/my-ui
is the URI of the plugin UI and
+my-ui.so
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.
+
+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-gtk:GtkUI. 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).
+
+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.
+
+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.
+
+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 not 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.

+The class which represents an LV2 plugin UI.
+
+
+To be used by a host a UI MUST have at least the following properties:
+
+ rdf:type (with object a proper subclass of pui:UI)
+ doap:name (one without language tag)
+ lv2:binary (with a shared object file as object)
+ lv2:appliesTo (with a LV2 plugin as object)
+
+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-gtk:GtkGUI 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.
+
+
+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.
+
+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
+instantiate() function, a host SHOULD NOT try to instantiate an UI if it
+doesn't support all of its required features, and an UI MUST fail to
+instantiate if the host doesn't pass all required features to instantiate().

-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
-
- @prefix ui: <http://lv2plug.in/ns/ext/ui#> .
- @prefix ui-gtk: <http://lv2plug.in/ns/ext/ui-gtk#> .
- <http://example.org/my-ui> a ui-gtk:GtkUI ;
- lv2:appliesTo <http://example.org/my-plugin> ;
- ui:binary <my-ui.so> .
-
-where http://example.org/my-plugin
is the URI of the plugin,
-http://example.org/my-ui
is the URI of the plugin UI and
-my-ui.so
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.
-
-A UI MUST specify its class in the RDF data and the class MUST be a proper
-subclass of ui:UI, in this case ui-gtk:GtkUI. 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).
-
-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.
-
-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.
-
-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 not 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
-ui.h is
-all you can expect to work.

- lv2:documentation """
-The class which represents an LV2 plugin UI.
-
-
-To be used by a host a UI MUST have at least the following properties:
-
- rdf:type (with object a proper subclass of ui:UI)
- doap:name (one without language tag)
- lv2:binary (with a shared object file as object)
- lv2:appliesTo (with a LV2 plugin as object)
-
-The rdf:type of an UI is used by the host to decide whether it supports the
-UI and how to handle the LV2_UI_Widget object that is returned by the UIs
-get_widget() function. For example, a type of ui-gtk:GtkGUI might tell the host
-that LV2_UI_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.
-
-
-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.
-
-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
-instantiate() function, a host SHOULD NOT try to instantiate an UI if it
-doesn't support all of its required features, and an UI MUST fail to
-instantiate if the host doesn't pass all required features to instantiate().
