%scriptUsurp()

    This function is "almost" exactly like the %scriptCall() function with one
    extremely useful difference. This runs the script owned by the owner
    entity which has the given name BUT when the script is run all commands
    are processed as though the entity calling the script were the actual
    owner of the script. This is useful because you could share an entire
    combat system in a script which is then invoked via %scriptUsurp() and
    thus processed as though the script had been defined for the entity
    itself. The parameters are passed to the script and assume the variable
    names the script itself sets out for them. This function is used in
    conjunction with the catch_call_script trigger type which is described in
    the triggers documentation. This combination is powerful but you may be
    looking for the solution provided by the %scriptCall() function which your
    are STRONGLY advised to read about now. Note that if the script returns a
    value you can retrieve it by assigning the value of the running the
    function.

    Example:

        %scriptUsurp( @n, "guardCombat" )
