Dear MathGroup,

Renan Cabrera, Jean-Francois Gouyet and I have completed a new Version 3.0
of the Tensorial package. It is available for download at

http://home.earthlink.net/~djmp/Mathematica.html


The package should be useful both as an introduction to tensor calculations
and for advanced calculations. Some of its features are:

1) There is complete freedom in the choice of symbols for tensor labels and
indices.
2) Base indices may be any set of integers or symbols. Thus you could use
{0,1,2,3} for relativity problems, or {t,x,y,z}, or {\[Rho],\[Theta],\[Phi]}
for spherical coordinates.
3) Flavored indices (colored or annotated symbols) to represent different
coordinate systems.
4) Tensor shortcuts for easy entry of tensors.
5) Easy methods to store and substitute tensor values.
6) Partial, covariant, total, absolute and Lie derivative routines.
7) Complete documentation, with a Help page and numerous examples for each
command. In addition there are tutorial and extended example notebooks.
