+ <dd>
+ <p>Return the set of all backends (i.e. their corresponding <code>EV_BACKEND_*</code>
+value) compiled into this binary of libev (independent of their
+availability on the system you are running on). See <code>ev_default_loop</code> for
+a description of the set values.</p>

+ <dt>unsigned int ev_recommended_backends ()</dt>
+ <dd>
+ <p>Return the set of all backends compiled into this binary of libev and also
+recommended for this platform. This set is often smaller than the one
+returned by <code>ev_supported_backends</code>, as for example kqueue is broken on
+most BSDs and will not be autodetected unless you explicitly request it
+(assuming you know what you are doing). This is the set of backends that
+<code>EVFLAG_AUTO</code> will probe for.</p>
