[ic] Process flow

[Jeff Fearn]

I was wondering if someone could give me an overview of the buy process 
sequence?

Specifically which files get called in which order through the ordering 
process.

i.e click the buy button, form submits order to <file> whith args <args> and 
perfomrs steps <steps>, then passes data to basket for display.

Now I'm betting that's fairly close, except for where the order actually 
gets munged into the cart.

Some nice data/control flow diagrams would be nice. Maybe the core guys 
could show us the ones they used for the design. I have looked through the 
docs and archive but have found little to help. I feel like it is staring me 
right in the face ... I hate that :}

Yours hopefuly, Jeff.
