+related tools at <http://lv2plug.in/>.  Contributions are welcome, please
+send patches to the LV2 mailing list (see admin page at
+<http://lists.lv2plug.in/> to subscribe or browse archives).
+
+Note that many components of this repository are experimental, and NOT
+suitable for release or packaging.
+
+The build system and documentation generation requires only Python
+and Doxygen.
+
+
+** Installing Core/Extension Bundles **
+
+./waf configure
+./waf
+sudo ./waf install
+
+The installation directory can be modified with the --lv2-dir or
+--lv2-user options to ./waf configure, e.g.:
+
+./waf configure --lv2-dir /path/to/dir/to/place/bundles/under
+
+or
+
+./waf configure --lv2-user
+
+which will install to the default user LV2 directory (e.g. ~/.lv2).
+
+
+
+** Generating Core/Extension Documentation **
+
+./gendoc.py
+
+Documentation output will be in build/default/doc.

+= LV2 Core package instructions =
+
+This package contains a header file, pkg-config file, and an LV2 bundle;
+there is no code that requires compiling (i.e. this is NOT a library).
+Accordingly, the versioning scheme is simpler than a library: the major
+number is the version number of the LV2 specification, and the minor
+number is the version of this package.  There is no 'micro' number.
+
+The configure option --bundle-only can be used to install only the bundle.
+This can be used in conjunction with the --lv2-user option to install
+only the bundle to the user-specific (i.e. in your home directory) LV2
+path, if you do not have write access to the system.
+
+Distribution packages should install everything, as apps may depend
+on 'lv2core' (via pkg-config) to ensure both the header and data
+bundle are present.

+* Build:           ./waf [OPTIONS]
+
+  Example:
+    ./waf
+
+
+* Install:         ./waf install [OPTIONS]
+
+  The environment variable DESTDIR can be used to add any prefix to
+  the install paths (useful for packaging).  Example:

+LV2
+---
+
+LV2 is a standard for plugins and matching host applications, primarily
+targeted at audio processing and generation.
+
+LV2 is a successor to LADSPA, created to address the limitations of LADSPA
+which many applications have outgrown.  Compared to LADSPA, all plugin data
+is moved from the code to a separate data file, and the code has been made as
+generic as possible.  As a result, LV2 can be independently extended
+(retaining compatibility wherever possible), and virtually any feasible
+plugin features can be implemented in an LV2 plugin.
+
+More information about LV2 can be found at <http://lv2plug.in>.
+
+This package is the "core" LV2 specification in usual source package form.
+The major version of this package refers to the LV2 specification revision
+contained, while the minor version refers only to this package.
+
+Application authors aren't required to depend on this package (including lv2.h
+in source distributions is acceptable) but any system with LV2 plugins should
+have the LV2 bundle contained in this package installed somewhere in the LV2
+path (it contains plugin classes and other useful information).
+
+Please see README file for installation instructions (this package doesn't
+really fit into the usual 'library', 'program', etc. categories).
+
+Distributions are encouraged to include this package.

+/** @file lv2.h
+ * C header for the LV2 specification <http://lv2plug.in/ns/lv2core>.
+ * Revision: 1
+ *
+ * == Overview ==
+ *
+ * There are a large number of open source and free software synthesis
+ * packages in use or development at this time. This API ('LV2')
+ * attempts to give programmers the ability to write simple 'plugin'
+ * audio processors in C/C++ and link them dynamically ('plug') into
+ * a range of these packages ('hosts').  It should be possible for any
+ * host and any plugin to communicate completely through this interface.
+ *
+ * This API is deliberately as short and simple as possible.
+ * The information required to use a plugin is in a companion data
+ * (RDF) file.  The shared library portion of the API (defined in this
+ * header) does not contain enough information to make use of the plugin
+ * possible - the data file is mandatory.
+ *
+ * Plugins are expected to distinguish between control rate and audio
+ * rate data (or other types of data defined by extensions). Plugins have
+ * 'ports' that are inputs or outputs and each plugin is 'run' for a 'block'
+ * corresponding to a short time interval measured in samples. Audio rate
+ * data is communicated using arrays with one element per sample processed,
+ * allowing a block of audio to be processed by the plugin in a single
+ * pass. Control rate data is communicated using single values. Control
+ * rate data has a single value at the start of a call to the 'run()'
+ * function, and may be considered to remain this value for its duration.
+ * Thus the 'control rate' is determined by the block size, controlled by
+ * the host.  The plugin may assume that all its input and output ports have
+ * been connected to the relevant data location (see the 'connect_port()'
+ * function below) before it is asked to run, unless the port has been set
+ * 'connection optional' in the plugin's data file.
+ *
+ * Plugins will reside in shared object files suitable for dynamic linking
+ * by dlopen() and family. The file will provide a number of 'plugin
+ * types' that can be used to instantiate actual plugins (sometimes known
+ * as 'plugin instances') that can be connected together to perform tasks.
+ * The host can access these plugin types using the lv2_descriptor()
+ * function.
+ *
+ * This API contains very limited error-handling.
+ *
+ * == Threading rules ==
+ *
+ * Certain hosts may need to call the functions provided by a plugin from
+ * multiple threads. For this to be safe, the plugin must be written so that
+ * those functions can be executed simultaneously without problems.
+ * To facilitate this, the functions provided by a plugin are divided into
+ * classes:
+ *
+ *  - Discovery class:     lv2_descriptor(), extension_data()
+ *  - Instantiation class: instantiate(), cleanup(), activate(), deactivate()
+ *  - Audio class:         run(), connect_port()
+ *
+ * Extensions to this specification which add new functions MUST declare in
+ * which of these classes the functions belong, or define new classes for them.
+ * The rules that hosts must follow are these:
+ *
+ *  - When a function from the Discovery class is running, no other
+ *    functions in the same shared object file may run.
+ *  - When a function from the Instantiation class is running for a plugin
+ *    instance, no other functions for that instance may run.
+ *  - When a function is running for a plugin instance, no other
+ *    function in the same class may run for that instance.
+ *
+ * Any simultaneous calls that are not explicitly forbidden by these rules
+ * are allowed. For example, a host may call run() for two different plugin
+ * instances simultaneously.
+ */
+

+
+
+/** Plugin Handle.
+ *
+ * This plugin handle indicates a particular instance of the plugin
+ * concerned. It is valid to compare this to NULL (0 for C++) but
+ * otherwise the host MUST NOT attempt to interpret it. The plugin
+ * may use it to reference internal instance data. */

+	 * shortnames, and roughly the same functionality.  URIs should
+	 * probably contain a version number (or similar) for this reason.
+	 *
+	 * Rationale:  When serializing session/patch/etc files, hosts MUST
+	 * refer to a loaded plugin by the plugin URI only.  In the future

+	 *
+	 * bundle_path is a string of the path to the LV2 bundle which contains
+	 * this plugin binary.  It MUST include the trailing directory separator
+	 * (e.g. '/') so that BundlePath + filename gives the path to a file

+	 * SHOULD NOT use this as a discovery mechanism, instead reading the
+	 * data file before attempting to instantiate the plugin).  This array
+	 * must always exist; if a host has no features, it MUST pass a single
+	 * element array containing NULL (to simplify plugins).
+	 *

+This extension defines a generic format for a typed piece of data, called an
+"atom" (e.g. integers, strings, buffers, data structures, etc).  Atoms allow
+LV2 plugins and host to communicate and store values of any type and size via
+a generic mechanism (e.g. port buffers, event payloads, shared data, etc.).
+Atoms are simple a chunk of memory with a type and a size, and are (with
+one exception) Plain Old Data (POD) and may be safely copied (e.g. with a
+simple call to <code>memcpy</code>).  Because they are POD, hosts and plugins
+can communicate atoms of any type, even if they do not understand that type.
+This allows two plugins that both understand some type to be used together in
+a host that does not itself understand that type, or allows a host to send
+atoms "through" a plugin that does not understand them (for e.g. routing,
+delaying, or buffering plugins).
+
+Atoms as defined by this extension can be trivially constructed in-place
+from events as defined by the <a href="http://lv2plug.in/ns/ext/event">LV2
+Event</a> extension.  A valid LV2_Atom (see atom.h) is contained within
+any valid LV2_Event (see event.h).  An LV2_Event is simply an LV2_Atom
+with a time stamp header prepended.  Atoms should be used anywhere a "value"
+needs to be stored or communicated, which allows implementations to be
+polymorphic and extensible.
+
+Optionally, the host MAY support "Blobs", which are dynamically allocated
+chunks of memory that (unlike Atoms) are not necessarily POD.  Blobs are
+accessed via references, which are a special case of Atom that always have
+type 0, are not POD, and can only be copied using host provided functions.
+This allows plugins and hosts to work with data of any type at all.
+Blob data MUST NOT be used in any way by an implementation that does not
+understand that blob type (meaningful type-oblivious use is impossible,
+e.g. the blob pointer may not point to actual memory).
+
+This extension requires the host to support the <a
+href="http://lv2plug.in/ns/ext/uri-map">LV2 URI Map</a> extension.

+/** @file
+ * C header for the LV2 Dynamic Manifest extension
+ * <http://lv2plug.in/ns/ext/dyn-manifest>.
+ * Revision: 1
+ *
+ * == Overview ==
+ *
+ * The LV2 API, on its own, cannot be used to write plugin libraries where
+ * data is dynamically generated at runtime (e.g. API wrappers), since LV2
+ * requires needed information to be provided in one or more static data (RDF)
+ * files. This API addresses this limitation by extending the LV2 API.
+ *
+ * A host implementing support for this API should first detect that the plugin
+ * library implements a dynamic manifest generator by examining its static
+ * manifest file, then fetch data from the shared object file by accessing it as
+ * usual (dlopen() and family) and using this API.
+ *
+ * The host is allowed to request regeneration of the dynamic manifest multiple
+ * times, and the plugin library is expected to provide updated data if/when
+ * possible. All data and references provided via this API before the last
+ * regeneration of the dynamic manifest is to be considered invalid by the
+ * host, including plugin descriptors whose URIs were discovered using this API.
+ *
+ * This API is extensible in a similar fashion as the LV2 plugin API.
+ *
+ * == Threading rules ==
+ *
+ * This specification defines threading rule classes, similarly to the LV2
+ * specification.
+ *
+ * The functions defined by this API belong to:
+ *
+ *  - Dynamic manifest open class:  lv2_dyn_manifest_open()
+ *  - Dynamic manifest close class: lv2_dyn_manifest_close()
+ *  - Dynamic manifest file class:  lv2_dyn_manifest_get_subjects(),
+ *                                  lv2_dyn_manifest_get_data()
+ *
+ * The rules that hosts must follow are these:
+ *
+ *  - When a function from the Dynamic manifest open or the Dynamic manifest
+ *    close class is running, no other functions in the same shared object file
+ *    may run.
+ *  - When a function from the Dynamic manifest file class is called, no other
+ *    functions from the same class may run if they are given at least one
+ *    FILE * argument with the same value.
+ *  - A function from the Dynamic manifest open class may not run after a
+ *    successful call to a function from the same class, in case a function from
+ *    the Dynamic manifest close class was not successfully called in the
+ *    meanwhile.
+ *  - A function from the Dynamic manifest close class may only run after a
+ *    successful call to a function from the Dynamic manifest open class.
+ *  - A function from the Dynamic manifest file class may only run beetween a
+ *    successful call to a function from the Dynamic manifest open class and the
+ *    following successful call to a function from the Dynamic manifest close
+ *    class.
+ *
+ * Extensions to this specification which add new functions MUST declare in
+ * which of these classes the functions belong, or define new classes for them;
+ * furthermore, classes defined by such extensions MUST only allow calls after
+ * a successful call to a function from the Dynamic manifest open class and
+ * before the following successful call to a function from the Dynamic manifest
+ * close class.
+ *
+ * Any simultaneous calls that are not explicitly forbidden by these rules are
+ * allowed.
+ */
+
+

+
+/** Dynamic manifest generator handle.
+ *
+ * This handle indicates a particular status of a dynamic manifest generator.
+ * The host MUST NOT attempt to interpret it and, unlikely LV2_Handle, it is NOT
+ * even valid to compare this to NULL. The dynamic manifest generator may use it
+ * to reference internal data. */

+ * Whenever a host wants to access data using this API, it could:
+ *
+ *  1. Call lv2_dyn_manifest_open();
+ *  2. Create an empty resource identified by a FILE *;
+ *  3. Get a "list" of exposed subject URIs using
+ *     lv2_dyn_manifest_get_subjects();
+ *  4. Call lv2_dyn_manifest_get_data() for each URI of interest, in order to
+ *     get data related to that URI (either by calling the function subsequently
+ *     with the same FILE * resource, or by creating more FILE * resources to
+ *     perform parallel calls);
+ *  5. Call lv2_dyn_manifest_close();
+ *  6. Parse the content of the FILE * resource(s).
+ *  7. Free/delete/unlink the FILE * resource(s).
+ *
+ * The content of the FILE * resources has to be interpreted by the host as a
+ * regular file in Turtle syntax. This also means that each FILE * resource
+ * should also contain needed prefix definitions, in case any are used.
+ *
+ * Each call to lv2_dyn_manifest_open() automatically implies the (re)generation
+ * of the dynamic manifest on the library side.
+ *
+ * When such calls are made, data fetched from the involved library using this
+ * API before such call is to be considered no more valid.
+ *
+ * In case the library uses this same API to access other dynamic manifests, it
+ * MUST implement some mechanism to avoid potentially endless loops (such as A
+ * loads B, B loads A, etc.) in functions from the Dynamic manifest open class
+ * (the open-like operation MUST fail). For this purpose, use of a static
+ * boolean flag is suggested.
+ */
+
+/** Function that (re)generates the dynamic manifest.
+ *
+ * handle is a pointer to an uninitialized dynamic manifest generator handle.
+ *
+ * features is a NULL terminated array of LV2_Feature structs which
+ * represent the features the host supports. The dynamic manifest geenrator may
+ * refuse to (re)generate the dynamic manifest if required features are not
+ * found here (however hosts SHOULD NOT use this as a discovery mechanism,
+ * instead of reading the static manifest file). This array must always exist;
+ * if a host has no features, it MUST pass a single element array containing
+ * NULL.
+ *
+ * This function MUST return 0 on success, otherwise a non-zero error code, and
+ * the host SHOULD evaluate the result of the operation by examining the
+ * returned value, rather than try to interpret the value of handle.

+ * operations on it at the end of the stream (e.g. use only fprintf(), fwrite()
+ * and similar).
+ *
+ * The dynamic manifest generator has to fill the resource only with the needed
+ * triples to make the host aware of the "objects" it wants to expose. For
+ * example, if the library exposes a regular LV2 plugin, it should output only a
+ * triple like the following:

+ * uri is the URI to get data about (in the "plain" form, a.k.a. without RDF
+ * prefixes).

+ * The dynamic manifest generator has to fill the resource with data related to
+ * the URI. For example, if the library exposes a regular LV2 plugin whose URI,

+ * http://www.example.com/plugin/uri, it should output something like:

+ *       lv2:binary <mylib.so>;

+This extension provides a mechanism for plugins to create new files for

+beyond what is explicitly guaranteed by this extension.
+
+To create a new file, plugins request a filename from the host.  This way,
+the host is aware of files used by the plugin and can use an appropriate
+location for them that the plugin alone could not know (e.g. using an
+appropriate disk volume for recording).
+
+Plugins may also use pre-existing files from elsewhere on the filesystem.

+    byte.</li>
+  
+  <li>Note On events with velocity 0 are not allowed. These events are
+  equivalent to Note Off in standard MIDI streams, but in order to make
+  plugins and hosts easier to write, as well as more efficient, only proper
+  Note Off events are allowed as Note Off.</li>
+  
+  <li>"Realtime events" (status bytes 0xF8 to 0xFF) are allowed, but may
+  not occur inside other events like they are allowed to in hardware MIDI
+  streams.</li>
+  
+  <li>All events must be fully contained in a single data buffer, i.e. events
+  may not "wrap around" by storing the first few bytes in one buffer and
+  then wait for the next run() call to store the rest of the event. If
+  there isn't enough space in the current data buffer to store an event,
+  the event will either have to wait until next run() call, be ignored,
+  or compensated for in some more clever way.</li>
+  
+  <li>All events must be valid MIDI events. This means for example that
+  only the first byte in each event (the status byte) may have the eighth
+  bit set, that Note On and Note Off events are always 3 bytes long etc.
+  The MIDI writer (host or plugin) is responsible for writing valid MIDI
+  events to the buffer, and the MIDI reader (plugin or host) can assume that

+This extension provides a mechanism for plugins to save and restore state
+across instances, allowing hosts to save configuration/state/data with a
+project or fully clone a plugin instance (including internal state).
+
+The motivating idea behind this extension is that a plugin instance's state
+is entirely represented by port values and a single key/value dictionary.
+This makes state well-defined and easily manageable by hosts.  Keys are URIs,
+avoiding conflicts and allowing the same dictionary to be used to store plugin
+state in any context.  Values are typed tagged (by URI mapped integers),
+but otherwise are simple binary blobs.
+
+This extension defines plugin instance state and provides a mechanism
+for saving/restoring it, but otherwise makes no restrictions on how a
+plugin works with state.  For example, other extensions may define dynamic
+ways to control plugin state at runtime.  The idea is that <em>all</em>
+plugin state can be represented with a single (conceptual) dictionary.
+This state representation is tried-and-true, universal, and works well with
+many existing technologies.  Accordingly, plugins/extensions that deal with
+instance state in any way SHOULD represent it in a way compatible with this
+extension, i.e. URI keys with URI-typed values.  Similarly, plugins SHOULD NOT
+use any other mechanism to store/restore state; this <strong>will</strong>
+cause serious problems, don't do it!  Note that you can store values of any
+format whatsoever, so if you have an existing state representation to use
+(e.g. XML), simply store it as a single value under some key.
+
+Files may be persisted using this extension in conjunction with the
+<a href="http://lv2plug.in/ns/ext/files">LV2 Files</a> extension.
+
+Instance state as defined by this extension is RDF compatible, allowing for
+simple and seamless integration with existing technology (LV2 or otherwise).
+An obvious benefit of this is that plugin state can be elegantly described
+in Turtle files; the persist:instanceState predicate is provided for this
+purpose.  RDF compatibility is also convenient since LV2 hosts are likely
+to already have mechanisms for working with RDF-style data.  Note, however,
+that hosts may store state in any way, and are not required to use any
+specific technology or file format to support this extension.

+properties of the instance form the predicate/object (respectively) of triples
+with a persist:InstanceState as the subject (see persist:instanceState
+for an example).  This may be used wherever it is useful to express a
+plugin instance's state in RDF (e.g. for serialisation, storing in a model, or

+Defines ports which contain string data.
+
+<h4>UI issues</h4>
+When using port_event / write_port (and possible other communication
+mechanisms), the format parameter should contain the numeric value of URI
+LV2_STRING_PORT_URI (mapped with http://lv2plug.in/ns/extensions/ui specified
+as map URI).
+
+It's probably possible to use ports belonging to message context
+&lt;http://lv2plug.in/ns/ext/contexts#MessageContext&gt; for transfer. However,
+contexts mechanism does not offer any way to notify the message recipient
+about which ports have been changed. To remedy that, this extension defines
+a flag LV2_STRING_DATA_CHANGED_FLAG that carries that information inside a
+port value structure.
+
+<h4>Storage</h4>
+The value of string port are assumed to be "persistent": if a host saves
+and restores a state of a plugin (e.g. control port values), the values
+of input string ports should also be assumed to belong to that state. This
+also applies to message context: if a session is being restored, the host
+MUST resend the last value that was sent to the port before session has been
+saved. In other words, string port values "stick" to message ports.

+string data MUST remain unchanged for the time a run() function of a plugin
+is executed. However, if the port belongs to a different context, the same
+data MUST remain unchanged only for the time a run() or message_process()
+function of a given context is executed.
+
+<h4>Output Port Semantics</h4>
+The plugin may only change the string or length in a run() function (if

+This extension defines a simple mechanism for plugins to map URIs to integers,
+usually for performance reasons (e.g. processing events typed by URIs in
+real time).  The expected use case is for plugins to map URIs to integers for
+things they 'understand' at instantiation time, and store those values for
+use in the audio thread without doing any string comparison.  This allows
+the extensibility of RDF with the performance of integers (or centrally
+defined enumerations).

+An extension for setting named/typed variables on an instance of an
+LV2 Plugin (or anything else).  A "variable" is really just a (reified)
+RDF statement with an implicit subject (e.g. the plugin instance).
+
+Variables serve as a portable, network transparent, and serialisable
+mechanism for clients (e.g. user interfaces, programs) to control any
+parameter of a running plugin instance.  Because variables are 'keyed'
+by URI (the predicate), future extensions can define variables with
+specific meanings or restricted/extended types.
+The value (rdf:value) of a variable may be anything, but hosts or plugins
+aren't guaranteed to support anything other than simple typed literals.
+Serialisation and code access to complex variables is considered outside
+the scope of this extension.
+
+Hosts and plugins SHOULD use the following types for appropriate values:
+
+<table>
+<tr><th>RDF Type</th><th>Data Type</th></tr>
+<tr><td>xsd:string</td><td>string</td></tr>
+<tr><td>xsd:decimal</td><td>floating point number</td></tr>
+<tr><td>xsd:integer</td><td>integer number</td></tr>
+<tr><td>xsd:boolean</td><td>boolean value</td></tr>
+</table>
+
+This extension does not currently define a code mechanism for access
+to variables.  A future revision, or a different extension, may.

+

+    or optional feature in it's RDF data.

+

+    been returned by the host-provided URI mapping function for a

+      single change if the host's UI thread has problems keeping up with the

+      thread the plugin is running in), @c buffer_size should be 4, the buffer

+      should contain a single IEEE-754 float, and @c format should be 0.

+

+      By default, the host should only call this function for input ports of

+      the lv2:ControlPort class. However, the default setting can be modified

+      by using the following URIs in the UI's RDF data:

+      uiext:noPortNotification

+      uiext:plugin

+      uiext:portIndex

+      </pre>

+      For example, if you want the UI with uri

+      <code><http://my.pluginui></code> for the plugin with URI

+      <code><http://my.plugin></code> to get notified when the value of the

+      output control port with index 4 changes, you would use the following

+      in the RDF for your UI:

+      <pre>

+      <http://my.pluginui> uiext:portNotification [ uiext:plugin <http://my.plugin> ;

+                                                    uiext:portIndex 4 ] .

+      </pre>

+      and similarly with <code>uiext:noPortNotification</code> if you wanted

+      to prevent notifications for a port for which it would be on by default

+      otherwise. The UI is not allowed to request notifications for ports of

+      types for which no transfer mechanism is specified, if it does it should

+      be considered broken and the host should not load it.

+

+      The @c buffer is only valid during the time of this function call, so if

+      the UI wants to keep it for later use it has to copy the contents to an

+      internal buffer.

+

+      This member may be set to NULL if the UI is not interested in any

+      port events.

+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
+<pre>
+@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>
+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.
+
+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.
+
+(Note: the prefix above is used throughout this file for the same URI)
+
+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.
+
+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
+<b>not</b> 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).
+
+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 as
+<pre>
+&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>
+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).
+
+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.
+
+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.
+
+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.

+This feature is ELF specific - it should only be used by UIs that

+If it is required by an UI the UI should also list a number of SO names

+depends on and that may not be unloaded during the lifetime of the host

+The host MUST then make sure that the shared libraries with the given ELF
+SO names are not unloaded when the plugin UI is, but stay loaded during
+the entire lifetime of the host process. On Linux this can be accomplished
+by calling dlopen() on the shared library file with that SO name and never

+@c ui:makeSONameResident feature, it MUST ALWAYS be safe for the host to
+just never unload the shared object containing the UI implementation, i.e.
+act as if the UI required the @c ui:makeResident feature instead. Thus
