Listens for middle mouse click events and clears the primary X selection (and cut buffers) on detection to avoid accidentially pasting stuff all over the place.
No need to disable your precious middle mouse button bindings, no clearing of visual selections nor performance losses because of emptying the primary X clipboard periodically. With the utilization of XInput and Xlibs this has no measurable impact on performance whatsoever. No elevated privileges required. Just run within your regular users' X session.
On Arch Linux you may simply use the AUR package.
For all other distros, please follow the instructions below.
