Old dog trying to learn some new tricks here.
For the first time in decades, I'm trying to learn a new programming language. Probably more accurately described as a scripting language - Python 2.X

There's a script that someone has written and it looks like it's designed to run from the command line interface, rather than being executed as a module. I'm having trouble following the included help file / Python's syntax for executing it. And I'm sure it's all down to my inexperience with Python. Hoping I can get some guidance.

The script help file is here:

I can't even get the help to display via the Python CLI! Any pointers / hints or tips?
Thanks in advance (and feeling like a dunce for not working it out on my own)
