        """
        Instantiates a new object responsible for writing data from the port 
        into a file.  The file name is given by the input_stream variable.

        It is important to notice that the porttype is a BULKIO__POA type and
        not a BULKIO type.  The reason is because it is used to generate a 
        Port class that will be returned when the getPort() is invoked.  The
        returned class is the one acting as a server and therefore must be a
        Portable Object Adapter rather and a simple BULKIO object.

        Inputs:
            <input_stream>    The X-Midas file to generate
            <porttype>        The BULKIO__POA data type
            <rem_file>        Removes the input_stream if present
