-define Package/libevent/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.
