Evrouter reads events from the Linux input layer, and, based on a user-specified set of rules, acts on them. Currently, evrouter can map events to X11 key and button presses, XMMS commands, and can also run shell commands.

Evrouter is intended to help legacy applications understand modern events such as mouse wheel movement, special keys on keyboards etc. It also offers hotkey-like functions, and can help existing modern applications deal with events that, for one reason or another, X11 is unaware of (as long as they are accessible through the Linux Event Layer).
