Like Guile itself, the Guile reference manual is a living entity, cared
for by many people over a long period of time.  As such, it is hard to
identify individuals of whom to say ``yes, this person, she wrote the
manual.''

Still, among the many contributions, some caretakers stand out.  First
among them is Neil Jerram, who has been working on this document for ten
years now.  Neil's attention both to detail and to the big picture have
made a real difference in the understanding of a generation of Guile
hackers.

Next we should note Marius Vollmer's effect on this document.  Marius
maintained Guile during a period in which Guile's API was
clarified---put to the fire, so to speak---and he had the good sense to
effect the same change on the manual.

Martin Grabmueller made substantial contributions throughout the manual
in preparation for the Guile 1.6 release, including filling out a lot of
the documentation of Scheme data types, control mechanisms and
procedures.  In addition, he wrote the documentation for Guile's SRFI
modules and modules associated with the Guile REPL.

Ludovic Court@`es and Andy Wingo, the Guile maintainers at the time of
this writing (late 2010), have also made their dent in the manual,
writing documentation for new modules and subsystems in Guile 2.0.  They
are also responsible for ensuring that the existing text retains its
relevance as Guile evolves.  @xref{Reporting Bugs}, for more information
on reporting problems in this manual.

The content for the first versions of this manual incorporated and was
inspired by documents from Aubrey Jaffer, author of the SCM system on
which Guile was based, and from Tom Lord, Guile's first maintainer.
Although most of this text has been rewritten, all of it was important,
and some of the structure remains.

The manual for the first versions of Guile were largely written, edited,
and compiled by Mark Galassi and Jim Blandy.  In particular, Jim wrote
the original tutorial on Guile's data representation and the C API for
accessing Guile objects.

Significant portions were also contributed by Thien-Thi Nguyen, Kevin
Ryde, Mikael Djurfeldt, Christian Lynbech, Julian Graham, Gary Houston,
Tim Pierce, and a few dozen more.  You, reader, are most welcome to join
their esteemed ranks.  Visit Guile's web site at
