-/**
- * Zend Framework (http://framework.zend.com/)
- *
- * This file exists to allow overriding the various output-related functions
- * in order to test what happens during the `Server::listen()` cycle.
- *
- * These functions include:
- *
- * - headers_sent(): we want to always return false so that headers will be
- *   emitted, and we can test to see their values.
- * - header(): we want to aggregate calls to this function.
- *
- * The HeaderStack class then aggregates that information for us, and the test
- * harness resets the values pre and post test.
