Trying to learn Tensors and understand how to input tensor equations into Maxima



I am learning Tensors (along with GR) and Maxima.

I would like to type in a work some of the examples
from my resource books such as:

	Relativity Demystified 
		by David McMahon and Paul M. Alsing
	Schaum's Tensor Calculus
		by David C. Kay
	A First Course in General Relativity 
		by Bernard F. Schutz

So far I have been reading Victor Toth's pages
and the manual but would greatly appreciate any
pointers you can offer or advice...

Victor Toth's Tensor and Maxima page(s):
http://www.vttoth.com/maxima.html

And his paper from Arxiv.org:
Tensor manipulation in GPL Maxima
http://arxiv.org/abs/cs.SC/0503073
