The Cadabra system

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. Cadabra is developed by Kasper Peeters and distributed under the GPL license.
