        This will create a Makefile and config.h appropriate for
        your system.

    3.  Build the program with:
            make

    4.  Test the results with:
            make check
        For a more demanding test run:
            make wringer

    5.  To preview where the program will be installed, use:
            make -n install
        To install the executable and manual page in the
        destinations shown by the above command:
            make install
        Depending on permissions of the destination directories,
        you may need to be super-user to perform the installation.
