Tochnog Updates and details.

Tochnog has been updated.

If you check Tochnog's website, you will find some changes and a few  
updates for Tochnog. The source files contain all the changes and  
enhancements incorporated by David Masin a few years ago. The version  
for Microsoft Windows build by David is also included and can be  
downloaded. We have also included a Linux version built using Ubuntu  
that contains the latest solver version of Superlu 4.0. Bear in mind  
that this is a 32-bit version.

We have also added a built up version of Tochnog for OSX built under  
Snow Leopard. However, it has been impossible to build it with Superlu  
4.0. The reason being that with the new 64-bit version of OSX )(Snow  
Leopard is a 64-bit system), the Superlu code gives error when  
executing which appear to be due to the fact that Superlu 4.0 uses  
integers as pointers. However in most of the new 64-bit system, an  
integer variable can not hold a pointer. Pointers need to be 64-bits  
otherwise the variables get truncated. We are working to overcome this  
problem.

Nevertheless, the OSX version in the website uses the Apple bulit  
Lapack library. Users may recall that the default solver for Tochnog  
uses Clapack, the C converted version of Lapack. As the Apple built  
Accelerate Framework includes 64-bit optimized versions of Lapack and  
Blas, the tochnog code can be linked against this framework and the  
instruction to build and link clapack deleted from the makefile.

We have included a Microsoft Word version of the user manual, a  
document describing the developements and additions made by David  
Masin entitled David Masin Additions, and a work in progress or living  
document that pretends to be a hands-on manual, which incorporates  
user experiences with Tochnog and Gid. The intention of this document  
is to be enhanced by suggestions and recommendations from other users.  
This document will be updated regularly.

Long live Tochnog! Let's continue to improve it!
