+<p>This document introduces you to the Symbian way of using OpenMAX IL Component
+Interface. </p>
+<section><title>Purpose</title> <p>OpenMAX IL Component interface is an ECom
+plug-in. This plug-in is loaded by OpenMAX IL Loader to access OpenMAX IL
+Component. </p> <p>The OpenMAX IL Component interface (entry point) is provided
+as a static library, and the ECom implementation is defined as a macro to
+allow OpenMAX IL Component to be built as an ECom plug-in with very little
+overhead. </p> </section>
+<section><title>API name library details</title><p>For Symbian OpenMAX IL
+Component functionality you must adapt the following static library file. </p> <table id="GUID-1B5B22D0-EE9B-5B88-BB47-FF91127F45CF">
