Background
Lua is provided in the wikitext by call to the parser function, which takes two mandatory arguments. The first is the page title in the module namespace, and the second is the method. In addition, there might be arguments to the method, but the method can also traverse the frames to fetch its arguments. The frames are available as special structures, and will be provided as the first argument to the method.

There are two different access models for the libraries. Some are set up as part of a core -structure, and some must be. It is not always obvious how a specific library is defined, and how it is accessed.
