What programming language(s) is the Cookbook implemented in?
The Cookbook is primarily implemented using features of the TWiki wiki, such as the ability to associate forms with wiki pages, and generate pages based on queries of page content and form data. In addition to this, the Cookbook uses a Scheme code formatter, implemented in Scheme, to format all of the Scheme code that appears in the Cookbook. Besides TWiki queries and some small patches to TWiki to integrate with Scheme, the Cookbook does not contain any custom script implemented in languages other than Scheme.
