The prototype Epsilon QVTr to QVTc to QVTu to QVTm to QVTp via QVTs to QVTi chain has been replaced by direct Java code.
A couple of QVTc and QVTr examples work both using interpreted and code generated Java.
However the chain is not yet mature enough for more than experimental use; graduation to 1.0.0 must wait a little longer.
