The <em>excalc</em> package is designed for easy use by all who are familiar
with the calculus of Modern Differential Geometry. The program is currently
able to handle scalar-valued exterior forms, vectors and operations between
them, as well as non-scalar valued forms (indexed forms). It is thus an ideal
tool for studying differential equations, doing calculations in general
relativity and field theories, or doing simple things such as calculating the
Laplacian of a tensor field for an arbitrary given frame.
