 4 rick  1.4  *  An extremely simple program that does (almost) nothing at all.

 5 rick  1.5  *    It illustrates how a module is called from a driver program, in this
 6            *    case a locally-provided main program rather than jsoc_main, and the
 7            *    use of the command line parsing features in (and outside of) the
 8            *    module.

 9 rick  1.1  *
10            *  Usage:

11 rick  1.5  *    smpl_00 [print= ...]

12 rick  1.1  *
13            *  Bugs:

14 rick  1.4  *    The program is of no particular use, and exists merely for heuristic

15 rick  1.1  *      and testing purposes.
16            *
17            *  Revision history is at end of file.
