description         A field theory approach to symbolic computer algebra
long_description    Cadabra is a computer algebra system for the \
                    manipulation of what could loosely be called \
                    tensorial expressions. It is aimed at, though not \
                    necessarily restricted to, theoretical high energy \
                    physicists. Because of its target audience, the \
                    program's interface, storage system and underlying \
                    philosophy differ substantially from other computer \
                    algebra systems.
