Pyjamas Web Widget Set

About: Pyjamas is a Python-to-Javascript compiler and an AJAX widget set for Web application development (its sister project is pyjamas-desktop).

The Pyjamas 0.5 Release brings significant improvements to not only the python-to-javascript compiler but also adds enhancements that can be used to dramatically reduce the amount of javascript deployed. Thanks to the use of dynamic module loading, python modules can now be compiled into their own javascript cache file, making it much easier for developers who use AJAX Widget Toolkits to integrate Pyjamas-generated Javascript into their applications.
