+SUMMARY="An event notification library"
+DESCRIPTION="The libevent API provides a mechanism to execute a callback \
+function when a specific event occurs on a file descriptor or after a \
+timeout has been reached. Furthermore, libevent also support callbacks due \
+to signals or regular timeouts.
+libevent is meant to replace the event loop found in event driven network \
+servers. An application just needs to call event_dispatch() and then add or \
+remove events dynamically without having to change the event loop."
