  // CS Grenade Drops on Death (a.k.a. CSNadeDrops) 0.14 by Avalanche
  //
  // When a player dies they will drop the grenades that they had
  // with them onto the ground for other players to pick up. The
  // grenades play a grenade-bouncing sound when they hit the ground
  // and they look just like the real grenades. This plugin was
  // requested by Danjal of the AMXX forums.
