This tool allows certain configurable actions to be taken upon events from `evdev` devices. These actions include feeding a new event back into a device (useful for button remapping) and running an arbitrary command. This tool **cannot** prevent the original event from being processed by other userspace programs listening for `evdev` events, for example ones using `libinput`. It was originally created because there currently is no way to give extra mouse buttons functionality when using Mutter.
## Long-Term Solution
The functionality of this tool should ideally be moved into `libinput` and/or Wayland compositors.
