Thanks, Jesse--I think you cleared it up in my head: and(x, y, z) = x y z or(x, y, z) = x | y | z xor(x, y, z) = x ^ y ^ z Thanks!

Status of AntUnit trunk?
Hi, the last AntUnit release has been made almost three years ago. In the meantime we've accumulated a few changes, one of which is needed by the EasyAnt folks (and I needed another one recently to debug some RAT Anttasks error). Therefore I'm entertaining the idea of a 1.2 release. AFAIR Gilles has put significant effort into a bridge that makes it possible to run AntUnit tests from within a JUnit test runner but I'm unsure of its state.
