mod_dtcl

mod_dtcl is an Open Source implementation of server parsed Tcl, running under Apache. It is a flexible platform that allows you to integrate Tcl and HTML however you choose; you can tightly interweave them, in order to write powerful dynamic web pages quickly, or you can also follow different programming models, such as the "Model View Controller" framework, should you wish to create a large, complex web system which seperates content from code.

Tcl is a very widely used and available scripting language with many years of development invested in it. Because Tcl is such a well known language, there is a large amount of documentation for it, both on the net and books. There are also many external Tcl modules that you can load into mod_dtcl, to create images, access databases, and so forth.

Note: mod_dtcl is still supported, but no longer under development. You should use Rivet if you are starting a new project. Otherwise, consider upgrading when it is convenient.
