-@c AUTHORS
-
-@c The Guile reference and tutorial manuals were written and edited
-@c largely by Mark Galassi and Jim Blandy. In particular, Jim wrote the
-@c original tutorial on Guile's data representation and the C API for
-@c accessing Guile objects.
-
-@c Significant portions were contributed by Gary Houston (contributions
-@c to POSIX system calls and networking, expect, I/O internals and
-@c extensions, slib installation, error handling) and Tim Pierce
-@c (sections on script interpreter triggers, alists, function tracing).
-
-@c Tom Lord contributed a great deal of material with early Guile
-@c snapshots; although most of this text has been rewritten, all of it
-@c was important, and some of the structure remains.
-
-@c Aubrey Jaffer wrote the SCM Scheme implementation and manual upon
-@c which the Guile program and manual are based. Some portions of the
-@c SCM and SLIB manuals have been included here verbatim.
-
-@c Since Guile 1.4, Neil Jerram has been maintaining and improving the
-@c reference manual. Among other contributions, he wrote the Basic
-@c Ideas chapter, developed the tools for keeping the manual in sync
-@c with snarfed libguile docstrings, and reorganized the structure so as
-@c to accommodate docstrings for all Guile's primitives.
-
-@c Martin Grabmueller has made substantial contributions throughout the
-@c reference manual in preparation for the Guile 1.6 release, including
-@c filling out a lot of the documentation of Scheme data types, control
-@c mechanisms and procedures. In addition, he wrote the documentation
-@c for Guile's SRFI modules and modules associated with the Guile REPL.

-@unnumbered Part IV: Guile API Reference
+This part of the manual explains the general concepts that you need to
+understand when interfacing to Guile from C. You will learn about how
+the latent typing of Scheme is embedded into the static typing of C, how
+the garbage collection of Guile is made available to C code, and how
+continuations influence the control flow in a C program.
+
+This knowledge should make it straightforward to add new functions to
+Guile that can be called from Scheme. Adding new data types is also
+possible and is done by defining @dfn{smobs}.
+
+The @ref{Programming Overview} section of this part contains general
+musings and guidelines about programming with Guile. It explores
+different ways to design a program around Guile, or how to embed Guile
+into existing programs.
+
+For a pedagogical yet detailed explanation of how the data representation of
+Guile is implemented, @xref{Data Representation}. You don't need to know the
+details given there to use Guile from C, but they are useful when you want to
+modify Guile itself or when you are just curious about how it is all done.

+@chapter Guile Implementation
+
+At some point, after one has been programming in Scheme for some time,
+another level of Scheme comes into view: its implementation. Knowledge
+of how Scheme can be implemented turns out to be necessary to become
+an expert hacker. As Peter Norvig notes in his retrospective on
+PAIP@footnote{PAIP is the common abbreviation for @cite{Paradigms of
+Artificial Intelligence Programming}, an old but still useful text on
+Lisp. Norvig's retrospective sums up the lessons of PAIP, and can be
+found at @uref{http://norvig.com/Lisp-retro.html}.}, ``The expert Lisp
+programmer eventually develops a good `efficiency model'.''
+
+By this Norvig means that over time, the Lisp hacker eventually
+develops an understanding of how much her code ``costs'' in terms of
+space and time.
+
+This chapter describes Guile as an implementation of Scheme: its
+history, how it represents and evaluates its data, and its compiler.
+This knowledge can help you to make that step from being one who is
+merely familiar with Scheme to being a real hacker.
+
+@menu
+* History:: A brief history of Guile.
+* Data Representation:: How Guile represents Scheme data.
+* A Virtual Machine for Guile:: How compiled procedures work.
+* Compiling to the Virtual Machine:: Not as hard as you might think.
