 * This is useful when a portal was installed under one URL and then
 * changed URL (or port), to ensure documents are not pointing to the
 * previous URL.
 * If enabled ($processQuiz = true), it will also process c_quiz,
 * c_quiz_question and c_quiz_answer.
 * This script is designed to be run from the browser, so maybe you
 * need to move it to an executable folder and change the first require.
