Cactus Code Thorn Exact
Authors    : Carsten Gundlach initially, plus many other authors.
CVS info   : $Header$
--------------------------------------------------------------------------

Purpose of the thorn:

The initial purpose of this thorn was the comparison of numerical
spacetimes against exact solutions.  One particular solution,
the boost-rotation-symmetric spacetimes, was the first application.

Later, the thorn developed as a reservoir for a variety of exact spacetimes,
some of them in different coordinate systems, and even some non-Einstein
spcetimes.  All od these exact spacetimes have been found useful for
testing different aspect of the code.  Since mamy different people have
contributed to this thorn by adding new exact solutions, you shoudl expect
many different styles of coding here.

For more details see the documentation in the directory doc.
