Abstract
A suite of computer algebra programs for tensor and spinor calculation s in torsion theories of gravitation is presented. Modules for the alg ebraic classification of curvature tensors in Riemann-Cartan space-tim es are discussed. The basic theoretical results and an algorithm for t he equivalence problem for Riemann-Cartan space-times are presented. T he package TCLASSI which implements this algorithm is also discussed.
