Laws of Computer Programming:
        (1) Any given program, when running, is obsolete.
        (2) Any given program costs more and takes longer.
        (3) If a program is useful, it will have to be changed.
        (4) If a program is useless, it will have to be documented.
        (5) Any given program will expand to fill all available memory.
        (6) The value of a program is proportional to the weight of its output.
        (7) Program complexity grows until it exceeds the capability of
                the programmer who must maintain it.
