All this is long gone in the past since the introduction of Zend_Application and the bootstrapping resource adapters. Zend introduced a standard bootstrapping mechanism into their framework. Many of the options from different framework components can now be configured in the applications configuration file application.ini. One problem persists although: the documentation. All the parameters for components like View, Session, Database etc. are documented either with the bootstrap resource, the component itself or both.

They've posted it to github complete with sections detailing:

• CacheManager
• Db
• FrontController
• Layout
• Navigation
• Router
• Translate

...and quite a few more. This is a great reference for anyone using the Zend Framework, no matter your experience level.
