Divmod Nevow is a web application construction kit written in Python. It is
designed to allow the programmer to express as much of the view logic as
desired in Python, and includes a pure Python XML expression syntax named stan
to facilitate this. However it also provides rich support for designer-edited
templates, using a very small XML attribute language to provide bi-directional
template manipulation capability.

Nevow also includes Divmod Athena, a "two way web" or "`COMET`_"
implementation, providing a two-way bridge between Python code on the server
and JavaScript code on the client.  Modular portions of a page, known as
"athena fragments" in the server python and "athena widgets" in the client
javascript, can be individually developed and placed on any Nevow-rendered page
with a small template renderer.  Athena abstracts the intricacies of HTTP
communication, session security, and browser-specific bugs behind a simple
remote-method-call interface, where individual widgets or fragments can call
remote methods on their client or server peer with one method: "callRemote".
