/*

    Henchman Inventory And Battle AI

    This file is used for options for the henchman ai.

    The exe and hak versions are different than the erf version.

    The exe and hak version still use the small scripts to control options.

    The erf version can just be built directly using this file without using
    the small control files, it can be changed to anything including
    module properties, spawn script, etc.
