Hello!

	This directory contains a tar file in which is a toolbox named 
	"cea", containing routines for lissajou Function and Hough transform.
	In addition to the tar file containing
	the toolbox is this README.  This README provides instructions for
	setting up and compiling the toolbox.

	First, acquire the "cea.tar.Z" file with "binary" mode set to 
	TRUE on ftp.  ( ftp> bin ). 

	Next, create a location for toolboxes if you have not already done
	so.  It doesn't matter where, but don't put it in $KHOROS_HOME/src.  
	You may want to create a $KHOROS_HOME/toolboxes, or some such location.
	Move the tar file to that directory.  

	Next, untar the toolbox with the command:
	% zcat cea.tar.Z | tar -xfoB -
                -OR-
        % uncompress -c cea.tar.Z | tar -xfoB -

	This will create the "cea" toolbox for you, with the conversion
	routines in it. I will refer to the path {toolbox location}/medic
	as the "top dir".


	Now, you will need to modify the "Toolboxes" file to get access to
	the new toolbox.  I recommend that you copy the file 
	$KHOROS_HOME/repos/Toolboxes to your own account unless you
	already have a personal Toolbox file.

	Set the KHOROS_TOOLBOX environment variable to this modified 
	toolbox file:  
	% setenv KHOROS_TOOLBOX {modified Toolbox file}
	As this will need to be done every time you log in, you may want to
	put it in your ".cshrc" file.

	Next, run kraftsman to add the toolbox to your KHOROS_TOOLBOX file.
	Specify the name "cea" for this toolbox. More information
	on kraftsman is available in Vol 2, Chapter 11 of the Khoros
	manual.

	Next, you will need to compile the routines.  If compiling a single 
	architecture, you must follow the steps below.  If you are compiling
	multiple architectures, please see Chapter 9 of the Khoros Programmer's
	Manual, on "Configuration Management".

	1) modify the {top dir}/repos/config/src_conf/cea_mf file.
	   - substitute your user name as the KHOROS_USER on line 32.
	   - substitute the absolute location to the LOCAL_SRC_TOP on 
	     line 39.  Use "\pwd" in the toolbox/src directory to 
	     get the absolute path, and replace /a/rocky/research/data4/cea/
	     with this path.
	2) cd {top dir}/src
	3) make Makefile Makefiles
	4) make install

	Finally, you will need to add {top dir}/bin to your path so that you
	will be able to execute the routines.  You may want to do this in your
	".cshrc" file, so that you will not have to remember to set the path
	every time you log in.
