RUR is a Python Learning Environment, based after Pattis's Karel the robot. More details can be found at http://rur-ple.sourceforge.net Version 0.9.0.1 is a bug-fix. Version 0.9 relied on the presence of a unicode version of wxPython (version 2.6 preferred). Version 0.9.0.1 should work with both the unicode and the ansi version of wxPython. André
