no-herd taviso@gentoo.org package likely has no upstream maintainer, taviso will accept all reported bugs. xse provides a way to send arbitrary XEvents to a window, sort of the opposite of xev(1). xse is basically a command line wrapper around the Xlib XSendEvent() function, allowing you to send any kind of event to X11 applications, such as input events, motion or configure notification, or any other. This can be useful for scripting interaction, debugging applications and experimenting with events while developing X11 applications.
