+<p>This extension defines two port types: morph:MorphPort, which has a
+host-configurable type, and morph:AutoMorphPort, which may automatically change
+type when a MorphPort's type is changed. These ports always have a default
+type and work normally work in hosts that are unaware of this extension. Thus,
+this extension provides a backwards compatibility mechanism which allows
+plugins to use new port types but gracefully fall back to a default type in
+hosts that do not support them.</p>
+
+<p>This extension only defines port types and properties for describing morph
+ports. The actual run-time switching is done via the opts:interface API.</p>
