+@title{Scribble: The Racket Documentation Tool}
+
+@author["Matthew Flatt" "Eli Barzilay"]
+
+Scribble is a collection of tools for creating prose
+documents---papers, books, library documentation, etc.---in HTML or
+PDF (via Latex) form. More generally, Scribble helps you write
+programs that are rich in textual content, whether the content is
+prose to be typeset or any other form of text to be generated
+programmatically.
+
+This document is itself written using Scribble. You can see its source
+at
+@(let ([url "http://git.racket-lang.org/plt/tree/HEAD:/collects/scribblings/scribble"])
+   (link url url)),
+starting with the @filepath{scribble.scrbl} file.
