          ZipTest is a utility for use with PC-Zipper to determine the
          optimum speed for your system.  The utility calls each procedure,
          executes a routine, times it, and then records the results.  Upon
          completion, ZipTest checks to find which procedure resulted in a
          negligible increase in processor speed.

          Optimum system performance results at the "crest" of the curve. 
          See the following graph example:


            |
            |
            |                                            *
          B |                       _|_ *
          E |                   *    |
          N |
          C |            *
          H |
          M |        *
          A |
          R |
          K |     *
            |
            |   *
            -------------------------|---------------------
                A B .....            K                   W


          In this example, ZipTest would recommend command line parameter
          "K" for use with PC-Zipper.

          Use of a higher parameter will not significantly increase your
          system speed and might cause errors if you have weak or defective
          memory chips.  If the use of ZipTest results in a system error
          before reaching completion, you probably have at least one
          defective memory chip.  Make note of the maximum speed reached and
          use PC-Zipper with a command line parameter several levels lower.
