********************************************************************************

tAo is a UNIX program to calculate the flexure of the lithosphere and, in
particular, to numerically simulate the formation of foreland basins. Please
read the 'tao/doc/tao.info.txt' file to know more about tAo.

Warning: TISC is a tool developed for my own research. I am not a  professional
programmer, the code is not exactly as user-friendly as a mobile app, and i
cannot guarantee assistance in case of  trouble. See other warnings in the
license file tisc/doc/copyright.txt.

When showing results of this program you should cite the following reference:

	modeling of foreland basin formation: a program relating thrusting, 
	flexure, sediment geometry and lithosphere rheology". Computers & 
	Geosciences, 23 (9), 993-1003.

tAo has been developed in ANSI C under UNIX operating system (AIX IBM). It has 
been also successfully compiled in linux UNIX PC and in a Hewlett Packard 
Workstation using HP UX.


TO INSTALL tAo:

-Uncompress and untar the file containing tAo using the unix command 
	'gunzip -c tao.tar.gz | tar -xvf -'
this will create directory 'tao/' in your current directory.

-Modify some compiling options by editing 'src/Makefile'.

-Compile typing  'make' in the main directory. This will create the executable 
tao in the bin/ directory. You should put tao/bin/ and tao/script/ in your path
and define the tao_dir variable in your environment.

-Optionally install GMT free-ware software (used for graphic output) and put 
its bin/ directory in your path. This should work:
	sudo apt-get update
	sudo apt-get install gmt ksh csh tofrodos

-Try examples of running tAo going to directory 'tao/demo/'. This will allow
you to be sure that the code is working properly. Check that the graphic
output is correctly produced in the postscript output files (*.ps)
