Kranc is a suite of Mathematica packages which comprise a computer algebra toolbox for numerical relativists - Kranc is designed to help wth tasks such as performing 3+1 decompositions, analytical manipulations of tensorial systems of equations such as change of variables, computation of characteristics or linearizations and automatized code generation.
The code generation part of Kranc can be used as a ``rapid prototyping'' system for physicists or mathematicians handling very complicated systems of partial differential equations, but through integration into the Cactus computational toolkit we can also produce efficient production codes.
The name Kranc stands for Kranc assembles numerical code.
