 #   Be nice if someone   
 #    - Took credit/blame for this module.  
 #    - At least commented the purpose of each major  
 #      sub  
 #    - Even better commented the major blocks.  
 #  
 #  I'll have a go at it for what I need.  
 #     ?'s- mean maybe this is right.

 #          of doubt I have about rightness, with ??? representing  
 #          uncertainty based on the first blush interpretation.

 #          ?  - I"m pretty sure I understand the code that backs up this  
 #               interpretation.
