strdup return of cmdparams_get_str()

/*
 *  smpl_00.c						$DRMS/proj/cookbook/
 *
 *  An extremely simple program that does (almost) nothing at all.
 *    It illustrates how a module is called from a driver program, in this
 *    case a locally-provided main program rather than jsoc_main, and the
 *    use of the command line parsing features in (and outside of) the
 *    module.
 *
 *  Usage:
 *    smpl_00 [print= ...]
 *
 *  Bugs:
 *    The program is of no particular use, and exists merely for heuristic
 *      and testing purposes.
 *
 *  Revision history is at end of file.
