wrapper
     
         Code which is combined with another piece of
        {code} to determine how that code is executed.  The wrapper
        acts as an interface between its caller and the wrapped code.
        This may be done for compatibility, e.g. if the wrapped code
        is in a different programming language or uses different
        calling conventions, or for security, e.g. to prevent the
        calling program from executing certain functions.  The
        implication is that the wrapped code can only be accessed via
        the wrapper.
