define Package/libevent2/Default/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.
