{# There are three blocks defined here that will be overridden in the other templates: {% block title %} will change the title displayed in the browser’s tab and window title. {% block header %} is similar to title but will change the title displayed on the page. {% block content %} is where the content of each page goes, such as the login form or a blog post. The base template is directly in the templates directory. To keep the others organized, the templates for a blueprint will be placed in a directory with the same name as the blueprint. g is automatically available in templates. Based on if g.user is set (from load_logged_in_user), either the username and a log out link are displayed, or links to register and log in are displayed. url_for() is also automatically available, and is used to generate URLs to views instead of writing them out manually. #}
