Description.txt

A Python web framework with embedded HTTP server on port 8888.
You can connect Python method with server.bind(func, name), where
server is serverlib.WebServer object, func is function to bind (
it must return str object), and name is URI for newly created page.
When you call run() method, the web server starts, and really binds functions
with URIs.
