// Package routecheck registers support for RouteCheck,
// which checks the reachability of overlapping routers.
//
// When there are multiple network paths to an IP address, it is being routed by
// overlapping routers. The client uses reachability to pick between those
// paths: either sticking with an active WireGuard session or choosing from the
// peers that it has determined it can reach. It doesn’t need reachability for
// IP addresses that have only one network path, since it can naively attempt to
// establish a WireGuard session.
