<P>S9fES is a mature, portable, and comprehensible interpreter for
R4RS Scheme. The core interpreter is written in pure ANSI C (C89), so it
runs on all platforms offering a C compiler. It can even be compiled
natively on Plan 9. On Unix-based systems (or MinGW), it also offers 
an interface to common <A href="ext.html">Unix system calls and
Curses routines</A>.</P>

<P>S9fES has been developed using <A href="edoc.html">EDOC</A>, a literate
programming tool. The (rendered) EDOC source code is only available in
<A href="../s9book/index.html">print and PDF form</A>. The C and Scheme
code stripped from the EDOC files is in the <EM>public domain</EM>, though,
and can be <A href="s9fes-$V.tgz">downloaded</A> here (~450KB).</P>

<P>The interpreter is explained in detail
in the <A href="../s9book/index.html">Scheme&nbsp;9 Book</A>!
