This makes them especially helpful for automated content generation and scripting.
Internally, the Lua commands are mapped onto their ConTeXt and TeX counterparts.
If you ever dreamed of proper typesetting without backslashes galore, here is where to start at.

Writing CLDs is straightforward although there are some pitfalls.
Suppose we want to typeset the following minimal example:
Mandatory (grouped) arguments are given either as strings or as functions.
The following example shows two ways of rewriting the above TeX code: the first one closely resembles its structure while the second calls the function <code>test</code> from inside the <code>placefigure</code> macro.

An alternative to the function encapsulation is provided by
