          <dc:description>A compiler and interpreter for Wyvern programming language written in Java and hosted on http://github.com/wyvernlang/wyvern and some sample programs (.wyv) including the main example from the paper in borderedwindow.wyv. We also include an extract of all the unit tests of which a large number may be designed to fail -- therefore they are best run using JUnit which can be done by checking out the source tree from the GitHub project link above.</dc:description>
