Matt, this really needs to be its own external package (unless you have written permission the author of tetgen?) before 3.3 is released. I don't think the license for tetgen jives with petsc's license, namely, tetgen doesn't allow commercial use (which petsc does) without contacting the author. If tetgen were an external package, then everything would be ok, I believe.</blockquote>
