GRTensorII

GRTensorII is a Maple package designed for tensor computations, particularly in general relativity.
This package was developed at Queen's University in Kingston, Ontario by Peter Musgrave, Denis Pollney and Kayll Lake. While there are many packages which perform tensor computations (including a "standard Maple package"), GRTensorII is particularly well suited for carrying out routine computations of useful quantities when working with (or searching for) exact solutions in general relativity. Its principal advantages include
Currently, GRTensorII does have some drawbacks:
