+ * Main loop abstraction layer. Both the PulseAudio core and the
+ * PulseAudio client library use a main loop abstraction layer. Due to
+ * this it is possible to embed PulseAudio into other
+ * applications easily. Two main loop implementations are
+ * currently available:
+ * \li A minimal implementation based on the C library's poll() function (See \ref mainloop.h)
+ * \li A wrapper around the GLIB main loop. Use this to embed PulseAudio into your GLIB/GTK+/GNOME programs (See \ref glib-mainloop.h)
+ *
+ * The structure pa_mainloop_api is used as vtable for the main loop abstraction.
+ *
+ * This mainloop abstraction layer has no direct support for UNIX signals. Generic, mainloop implementation agnostic support is available through \ref mainloop-signal.h.
