The Tcl Tensor package allows for the creation and manipulation of
multidimensional numerical arrays. This is an update of code I wrote
many moons ago for work done at General Motors R&D, and previously
released in source form as the "Tns" package. The new version, 4.0a1,
updates the code to use the Tcl_Obj interface, has a TEA-compliant
build system, puts tensor commands in their own namespace, and adds a
tensor::expr command for computing tensor expressions.

This is the first alpha release, but it has a fairly complete test
suite (except that the tensor::expr command should be tested more
thoroughly), which it passes. It has been built on both Fedora Linux
and Windows XP. The code is available at
