The Mozart Programming System is the primary implementation of Oz. It is released with an open source license by the Mozart Consortium. Mozart has been ported to different flavors of Unix, FreeBSD, Linux, Microsoft Windows, and Mac OS X.[2]
How to execute the examples on Rosetta Code
All examples that start with declare can be used directly in the Emacs-based IDE, without a separate compilation step. Just copy the source code to the Oz buffer and select the menu item "Oz→Feed Buffer".
Some examples are functor definitions and must be compiled. The compiler is invoked with a command such as: ozc -c filename.oz, and then executed with the command, ozengine filename.ozf. This [https://stackoverflow.com/a/29207029/371304 Stack Overflow answer] shows an example of the boilerplate to transform code written for the Emacs IDE to code that can run directly on the Mozart VM.
