[fw-general] Working with Paths

[fromvega]

Hello,

I'm not currently using Zend Framework although I'm observing it's 
evolution waiting for the final release and studying its applicability 
into my projects.

One thing that poped into my mind lately is how I should deal with paths 
within Zend Framework. Is there any built in solution for this? For this 
I mean a way to reference the application base directory and define 
other key directories to be used in the code instead of writing the path 
everytime.

I'm used to create constants to define paths. What about Zend Framework? 
What about modules that have they own javascript and css files for 
instance? How should I organize them?

Thank you,
Luiz
