Nature of problem:
Strings and traces of gamma-matrices are calculated mathematically consistent in arbitrary space-time dimensions according to the 't Hooft- Veltman scheme, or alternatively with anticommuting gamma5. Many additional functions to modify resulting expressions are implemented.

Solution method:
Implementation of the algebraic rules given in the following: G. 't Hooft and M. Veltman, Nucl. Phys. B44 (1972) 189. and P. Breitenlohner and D. Maison, Comm. Math. Phys. 52 (1977) 11.

The number of gamma-matrices that can be processed strongly depends on the machine speed and the computers physical amount of memory, especially in the t'Hooft-Veltman scheme.

Running time:
The typical running time strongly depends on the complexity of the calculated gamma-algebra expression.
