    cfitsio_dir - location of cfitsio distribution

    This small script runs each of the testprog*.pl scripts, validating
    their outputs against the output of the testprog.c program which
    comes with cfitsio. It should be called with the location of the
    normal cfitsio (not Astro::FITS::CFITSIO) distribution
