Code only, but the an abstract of the paper can be read online: http://iakswww.ira.uka.de/iakscalmet/werner/Abstracts/IMACS95.ps.gz Orignal code can be downloaded from here: http://axiomwiki.newsynthesis.org/public/JetJune1995.tar.gz I wish to thank Werner Seiler for digging up this code and granting permission to use it, and apologize for not announcing this sooner  it was actually online back in late December.
