See http://web2py.com/books/default/chapter/29/05/the-views#The-views for
an explanation of how the views work. Everything inside the {{...}}
delimiters is executed as Python code. Each line or fragment that is
outside of the delimiters is considered a string literal to be written
directly to the response body (by wrapping it in response.write()). So, the
Python code in the view gets executed on the server. The resulting HTML is
then sent to the browser, and the Javascript that was written into the HTML
gets executed in the browser.
