Template Data Interface (TDI, /ʹtedɪ/) is a markup templating system written in Python with (optional but recommended) speedup code written in C. Unlike most templating systems, TDI does not invent its own language to provide functionality. Instead, you simply mark the nodes you want to manipulate within the template document. The template is parsed, and the marked nodes are presented to your Python code, where they can be modified in any way you want.
