Nature of problem:
Calculation and manipulation of tensors of General Relativity. This package can be used to obtain field equations for a given metric in coordinate or vierbein basis. New tensor equations can be defined and manipulated.

Solution method:
A wide variety of algorithms has been used. A great effort has been made to develop interface and efficiency.

Restrictions:
Computer memory.

Running time:
Calculation of the Riemann tensor of the Schwarzschild metric takes less than 1 second for most workstations and personal computers.
