* Command Line Parsing routines

* parsing across an array of tools. The tools should obey the historical
* rules of:
*
* (1) one command per line,
* (2) the command should be uppercase,
* (3) options should be lowercase,
* (4) a short usage statement is presented in case of error,
* (5) a long usage statement is given by -? or --help
