Riemann is a Maple package for calculating components of user-defined or built-in tensors used in General Relativity. One must define the metric or the tetrad in order to calculate tensor components. Riemann tensor package can calculate scalars or components of tensors generated by the Canon tensor package.

The package has been named in honor of G.F.B.Riemann, the German mathematician who generalized Gauss work on differential geometry. Riemann's ideas were used by A.Einstein as the mathematical background of the General Relativity theory.
