[PyGreSQL] Questions on http://www.druid.net/rides/

[Ms Soo Chong]

Hi all,

is me again... 

I have question on http://www.druid.net/rides/index.txt. This provides a good example for me but I don't really know exactly what each line does (majority part). So, can someone or the author himself help to clarify my doubts by explaining the major part of the code to me. 

Your help is very very much appreciated and I need that badly.

Thank you for any help.
