* \brief Stasis application support.
*
* \author David M. Lee, II <dlee at digium.com>
+ *
+ * <code>res_stasis.so</code> brings together the various components of the
+ * Stasis application infrastructure.
+ *
+ * First, there's the Stasis application handler, stasis_app_exec(). This is
+ * called by <code>app_stasis.so</code> to give control of a channel to the
+ * Stasis application code from the dialplan.
+ *
+ * While a channel is in stasis_app_exec(), it has a \ref stasis_app_control
+ * object, which may be used to control the channel.
+ *
+ * To control the channel, commands may be sent to channel using
+ * stasis_app_send_command() and stasis_app_send_async_command().
+ *
+ * Alongside this, applications may be registered/unregistered using
+ * stasis_app_register()/stasis_app_unregister(). While a channel is in Stasis,
+ * events received on the channel's topic are converted to JSON and forwarded to
+ * the \ref stasis_app_cb. The application may also subscribe to the channel to
+ * continue to receive messages even after the channel has left Stasis, but it
+ * will not be able to control it.
+ *
+ * Given all the stuff that comes together in this module, it's been broken up
+ * into several pieces that are in <code>res/stasis/</code> and compiled into
+ * <code>res_stasis.so</code>.
