Notes on byterange presentation script:

    Under DECC, byterange.c must be compiled /prefix=all

    link byterange.obj with time_util.obj (time_util.c included),
    cgilib.obj, and scriptlib.obj.  Place executable in www_system ([-.system]
    directory) since program is a presentation script and not an exec script.

    Add following line to http_suffixes.conf:

	suffix .pdf application/pdf BINARY 1.0
	presentation application/pdf byterange

    (add additional presentation rules to suit).
