"libevent, 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.")
