I wanted to update the maven install (mvn clean install) but I get the
error that
http://repo1.maven.org/maven2/org/antlr/gunit/1.0.5/gunit-1.0.5.jar
can't be found. :(
In any case, Ter, did you you try the CSharp2 version of the
composite-grammar, too? That way we can check, if this is just a local
problem.

P.S.: I'm not off for bed for two hours or so. You Americans should get
