 4 rick  1.2  *  Annother simple module that does nothing but echo back the values of
 5            *    arguments. It illustrates the use of command line parsing and the
 6            *    variety of argument types; also introduces time string functions

 7 rick  1.1  *
 8            *  Usage:

10            *
11            *  Bugs:
12            *    The module is of no particular use, and exists merely for heuristic
13            *      and testing purposes.
