Subject: Carbone Ruby VM

hi all,

let me notify you that I imported the Carbone Ruby VM into it's project
space at savannah.

It's project page is: http://savannah.gnu.org/projects/carbone/

http://www.freesoftware.fsf.org/carbone/README.html

Carbone Ruby VM
======================

Carbone  is a  vmgen based,  efficient virtual  machine for  Ruby.  It
targets compatibility, performance and portability.

Anton  Ertl's vmgen  is  originally  the build  tool  for Gforth,  the
fastest portable Forth implementation. It produces VMs that use direct
threaded  code  and  support   various  optimizations  that  make  the
execution of a virtual machine less virtual (i.e. faster).

There is lots  of flexibility gained in the decision  to use vmgen; to
name the most important: VM instructions can be coded in C

What's already working in the Carbone VM is:
  * sending
  * generically calling C functions
  * parts of the Ruby object system
  * defining classes
  * defining methods
  * defining procs
  * calling methods, procs
  * instance variables for classes
  * Fixnum


This  is a  developers-only prerelease  of  Carbone. BTW  there is  no
compiler  yet.    Neither  forward  nor   backwards  compatibility  is
guaranteed! You have been warned.

Carbone is released under the GPL.  Parts will be under LPGL.  I think
about adopting the Guile Copyright.

The preferred way for support and especially the exchange of ideas and
patches is
            carbone-dev@mail.freesoftware.fsf.org

and more occasionally than regularly irc (#ruby-lang).


Carbone's author till now is Markus Liedl <markus.lado@gmx.de>

Dependencies
------------

  Gforth snapshot from May 2001,
  which includes vmgen
                    http://www.complang.tuwien.ac.at/anton/vmgen/
                    also see the paper there.

  Bison, Flex

  Ruby, M�taRuby    for preprocessing Fixnum-Builtins to C/vmgen code
                    www.ruby-lang.org,
                    cvs.ruby-lang.org:/src/lib/metaruby
                    (also changes neccessary in configuration.rb:
                      $options[:metaruby] = "/..../src/lib/metaruby")

  GCC               preferably version 3; but 2.x works also fine
		    (you may have to adjust configuration.rb:
                      $options[:has_gcc_3_0] = true; ...)

  Boehm GC          optional; for example Debians libgc6 and libgc6-dev

  Till now it's running it on Linux.
