================= WebTK v0.alpha3 ================= Find a new alpha-release of WebTK: http://www.webtk.org/ It includes a brand new data model (featuring data events!), a Forum application and a refactored module architecture. The examples below have been updated to reflect changes. What is WebTK ? =============== WebTK is a Python framework, using Twisted as its underlying Web server, and allowing webmasters to develop websites like any classic GUI software. It is object-oriented, providing and handling event-based widgets. It also does not need any database to work, as it uses objects persitance, with the help of PyPerSyst. Disclaimer ========== Please note that the alpha series are mainly for developers that want to have a look at WebTK internals - there are plenty of bugs, dirty tricks and the installation is not easy. This is NOT for production websites.
