@title{Scribble's Extensibility}

Scribble's foundation on PLT Scheme lets us to implement a number of
features as libraries that ordinarily must be built into a
documentation tool. More importantly, users can experiment with new
and more interesting ways to write documentation without having to
modify Scribble's implementation.

In this section, we describe of three libraries that we have already
built: one for API documentation, one for automatically running
examples when building documentation, and one for combining code with
documentation.
