Open Source Release Announcement

IBM Research releases the following files as open source under the Eclipse Public License - v 1.0. Use is permitted within the license restrictions.

The software released here comprises the Renaissance Virtual Machine (RVM) and Smalltalk code, which runs on a Smalltalk environment and implements support code for the RVM as well as an extension to the Smalltalk language called Sly3. All parts of this release have been developed as part of the Renaissance project at IBM Research.

The RVM was designed and implemented by David Ungar and Sam Adams.
The Smalltalk support code and the Sly language was implemented and designed by David Ungar and Sam Adams, too.
The RVM was ported to x86 multicore processors by Stefan Marr, Software Languages Lab, Vrije Universiteit Brussel.
