Wheefun Presentation Layer

WFPL is a framework for implementing web pages using the model-view-controller (MVC) design pattern. In WFPL, documents are represented abstractly using a hierarchical "Page" structure, which are then rendered using a renderer which may represent media such as HTML, TeX, or Markdown. The controller is frequently implemented as a callback script in the case of a webpage.

WPFL's strengths lie in its hierarchical design; it is similar to HTML/XML's document object model and provides a number of basic nodes. It is meant to be lightweight and low-level; it eschews concerns such as theming, but such concerns are thought to be easily facilitated through it.
