-<p>An extension for LV2 plugins which have several execution contexts.</p>
-
-<p>Contexts allow plugins to run tasks and/or process input/output in
-multiple threads. Contexts can be used to add non-realtime functionality
-to a plugin while still keeping the audio run() method realtime safe.</p>
-
-<p>A context is an LV2 feature, so the usual LV2 feature mechanism is used
-to determine whether a plugin has a given context, and whether or not it is
-mandatory.</p>
-
-<p>Unless otherwise stated, each context (defined by some URI) adds a new
-threading class similar to the Audio class defined by LV2. Each context has a
-run callback and a connect_port callback both in the same class (i.e. can't be
-called concurrently), but may be called concurrently with functions for other
-contexts (excluding the Instantiation class). Context properties such as
-ctx:hardRTCapable apply to both functions.
-The host MUST only call the correct connect_port function associated with the
-context for that port, i.e. it is an error to use the main LV2 connect_port
-function on a port with a context other than the main LV2 run function.</p>

-
-<p>Ports are always associated with a context. If a port has no explicit context
-property, then its context is ctx:audioContext (the default LV2 run() context).</p>
-
-<p>A plugin indicates support for a context by supporting an LV2 Feature with
-that context's URI. If a plugin optionally supports a context (e.g.
-<code>&lt;plugin&gt; lv2:optionalFeature ctx:idleContext .</code>), then
-all ports associated with that context MUST be lv2:connectionOptional. Thus,
-hosts that do not support contexts will connect such ports to NULL and the
-plugin can run with only a standard LV2 run() context.</p>
-
-<p>Any plugin that supports any context (optionally or mandatorily) MUST adhere
-to the following additional threading rules for LV2_Descriptor.connect_port:</p>

-<li>connect_port MUST only be called for a given port from the context

-contexts (but MUST NOT be called concurrently for multiple ports in the
