+/**
+ * @class ACE_FlReactor
+ *
+ * @brief A Reactor implementation that uses the Fast-Light (FL) toolkit
+ * for event demultiplexing. This will let us integrate the FL
+ * toolkit with ACE and/or TAO.
+ *
+ * As many other GUI toolkits FL supports a minimal set of
+ * callbacks to handle event demultiplexing, namely simple methods
+ * to add file descriptors to the event demuxing set or timeout
+ * events. This class adapts this simple mechanisms so they are
+ * compatible with ACE's Reactor.
