README file for Gambit-C version 2.2 (May 10, 1995)
====================================


This software is Copyright (C) 1994, 1995 by Marc Feeley, all rights reserved.


This directory contains the first public release of the Gambit-C
programming system (version 2.2).  Gambit-C includes a Scheme
interpreter and compiler which can be used to build standalone
executables.  Because the compiler generates portable C code, it
should be fairly easy to port to any machine with a decent C compiler.
The Gambit-C system has been built successfully on the following
machine/OS configurations:

 - SUN4 with Solaris 2.4
 - SUN4 with SunOS Release 4.1.4
 - SGI Indy with IRIX 5.3
 - DEC Alpha with OSF/1 V3.0 (Rev. 347)
 - HP9000/720 with HP-UX A.09.01 A
 - HP9000/340 with HP-UX B.08.00 A
 - IBM RS6000 with AIX 3.2
 - Apple Macintosh with MachTen 2.1.1g
 - Apple Macintosh with CodeWarrior 1.0
 - PC 386 with Linux Slackware 1.2.0
 - PC 386 with NetBSD/i386 1.0
 - PC 386 with MS-DOS (using DJGPP 1.12)


The Gambit-C system conforms to the R4RS and IEEE Scheme standards.
The full numeric tower is implemented, including: infinite precision
integers, rationals, inexact numbers, and complex numbers.  Gambit-C
supports a number of extensions to the standards including:

 - a debugger with a stack inspection facility (i.e. "backtrace")
 - a foreign function interface for C
 - dynamic loading of compiled modules (if the OS supports dynamic linking)
 - pretty printing
 - string ports
 - structures
 - eval


Read the file INSTALL for installation instructions.

The file USER.ps contains a user manual for the system.

The file C-INTF describes Gambit-C's foreign function interface.
