This is from the NEWS file: - color and clifford classes are functional and documented. - New "spinidx" class for dotted/undotted indices. - Predefined spinor metric tensor (created by spinor_metric()). - Symbols can have a LaTeX name, e.g. symbol s("s", "\\sigma"); - LaTeX output of indexed objects is much nicer. - Fix some build-problems (with recent libreadline). (*) - Semantics of arithmetic operators now follows the C++ rules more strictly. (*) Hi Julian! ;-) Enjoy -richy. -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/>
