//
// Some notes and thoughts:
//
// This code is designed NOT to remove weapons that are
// hand-placed by level designers. It should only clean
// up weapons dropped by dead NPCs, which is useful in
// situations where enemies are spawned in for a sustained
// period of time.
//
// Right now we PREFER to remove weapons that are not in the
// player's PVS, but this could be opposite of what we
// really want. We may only want to conduct the cleanup on
// weapons that are IN the player's PVS.
