Need some help

[eluser]Unknown[/eluser]
Hi, I'm quite experienced in PHP but this is the first time I have really considered using a framework like this.

I have a few questions about making a website more dynamic.

Okay, first question.

I know of course how I would go about making this sort of thing from scratch, but I just don't know the proper way of doing it with this framework. How would I go about making a dynamic title that can be called throughout the whole system like this in my templates:

Code:

<title>{site_title}</title>

Second question.
How do I go about loading classes in each one of my scripts without having to include them each time?

Thanks for any help.
