plugins/hooks/hacks quick question
 

Hello people, i really apologize for the noddy question.

I understand a little php, sql and i grasp the concept of xml but i need pointing in the right direction.

I'm looking for an overview of how the vbull software generates pages and which files it uses. I can see loads of info on specific items like creating hooks/plugins etc. But i want an overview becuase i don't really understand how it all fits together.

and another question. if i wanted to hack in some php to a global variable and call it anywhere within the templates, which file should i hack the php into. It seems to get very upset in global for example.

Thanks in advance.
