Scribble: PLT Documentation Tool

Scribble is a collection of tools for creating prose documents, especially those that document libraries, and especially for HTML and PDF (via LaTeX) output. More generally, it is useful for cases where you need to deal with Scheme code that is rich in textual content: it has a syntactic extension for writing almost free-form text and a tool for using the scribble syntax for preprocessing text files.

This document itself is written using Scribble. At the time that it was written, its source was available at http://svn.plt-scheme.org/plt/trunk/collects/scribblings/scribble/ starting with the "scribble.scrbl" file.
