The Tcl Web Application Framework helps simplify writing Web applications in the Tool Command Language (Tcl). It provides the features that form the basis for writing an application, such as sessions, users, privilege separation, and an abstract database interface. It is currently under development, but stable for production use.
It is written in such a way that applications can integrate into the framework without having to modify the framework itself, making upgrading the framework without breaking the application possible.
Feedback and suggestions are appreciated as this project matures.
