+ * \brief Describes the codec algorithm interface to applications.
+ *
+ * This file describes the interface between an application and a
+ * video codec algorithm.
+ *
+ * An application instantiates a specific codec instance by using
+ * vpx_codec_init() and a pointer to the algorithm's interface structure:
+ *     <pre>
+ *     my_app.c:
+ *       extern vpx_codec_iface_t my_codec;
+ *       {
+ *           vpx_codec_ctx_t algo;
+ *           res = vpx_codec_init(&algo, &my_codec);
+ *       }
+ *     </pre>
+ *
+ * Once initialized, the instance is manged using other functions from
+ * the vpx_codec_* family.
