grapp15.zip: Grappling hook v1.5 (replaces grapp12.zip)
    A collection of Quake mods centered around a grappling hook that uses
    a realistic physics model! Swing like Tarzan, knock your enemies into
    lava and snipe from the ceiling!  Other mods include conservation of
    momentum (you can push people!), frog leaps and a kamikaze key.
    Unique self-binding feature makes this mod incredibly easy to use:
    no more console commands.  One keystroke activates all the commands
    and gives you help, too!
