   File:        CheckVer.c

   Description: Takes version numbers of software (or anything else for that matter)
                Compares them and then returns:

                0 - Older -  The version passed is older than the required version
                1 - Newer or matching - The version passed is at least the required version
                -1 - some kind of error condition

                This is a very simple program so very little error checking is done.
