4 Bottle is a fast and simple micro-framework for small web applications. It
5 offers request dispatching (Routes) with URL parameter support, templates,
6 a built-in HTTP Server and adapters for many third party WSGI/HTTP-server and
7 template engines - all in a single file and with no dependencies other than the
8 Python Standard Library.
