Overview
Cuca Application
A Cuca::App object will be created directly by the dispatcher - which again is the direct cgi or fastcgi script that get run by the webserver. Normally you just create a Cuca::App object and run the cgicall function with optional with a cgi object as paramenter. Before doing that you must set $cuca_path to the root of your appication structure.
