SHEEP is a computer algebra system designed primarily for the needs of General Relativity, but it can also be used in other fields.

SHEEP can:

- Read, write, simplify, substitute into and differentiate algebraic expressions.
- Define tensors and tensor algorithms.
- Manipulate tensor components.
- Calculate the Einstein tensor from a given metric in a tetrad or in a coordinate frame.
- Perform perturbation calculations. (Not yet in SHEEP2).

More information about SHEEP can be found in the Standard SHEEP Letter. The lectures notes of J. Skea on SHEEP give a very good overview of SHEEP's features and applicability.
