    This is an example of how to use the
    new default module events for NWN to
    have all code concerning one item in
    a single file.

    Note that this system only works if
    the following scripts are set in your
    module events

    OnEquip      - x2_mod_def_equ   (or mi_zep_onequip)
    OnUnEquip    - x2_mod_def_unequ
    OnAcquire    - x2_mod_def_aqu
    OnUnAcqucire - x2_mod_def_unaqu
    OnActivate   - x2_mod_def_act
