** ObjectiveAmiga: Interface to class RexxHost

// This class provides an easy way to add an ARexx host to any ObjectiveAmiga
// application. Simply create a descendant of RexxHost with the desired ARexx
// command methods (called '-rxc<UPPER_CASE_COMMAND_NAME>' and run it through
// your Application object (-runFromAppKit).
