What are Zend_FrontController and its responsibilities?

Answer: `Zend_FrontController` is a central component in the Zend Framework that manages the flow of an application. Its primary responsibilities include:

1. Request Routing: It receives incoming requests and determines which controller and action to execute based on the request URI.
2. Controller Initialization: It initializes the appropriate controller and action method, handling dependencies and instantiation.
3. Response Handling: It manages the response object that is sent back to the client after processing the request.
4. Plugin Integration: It supports the use of plugins to modify the request-handling process, allowing for pre- and post-processing of requests.

Overall, `Zend_FrontController` acts as the main entry point for a Zend Framework application, orchestrating the request lifecycle.
