read_haloe_l2.README 6/14/04

To install the GSFC DAAC "read_haloe_l2" tool, the user will first have to 
uncompress and untar the read_l2_haloe.tar.Z file.  This file contains the 
Makefiles and the source codes for all the instrument read programs (both C 
and Fortran versions).  Enter the command

		uncompress -c read_haloe_l2.tar.Z | tar xvf -

* Once uncompressed and untared, this file is approximately 48 MBytes.

This will create the following directories and source files within a new
directory called "readump"

	readump/
	readump/Makefile  
	readump/bin/
	readump/src/
	        src/READ_HALOE_L2.F
	        src/read_haloe_l2.c

Create the executables in a bin directory by changing to the readump directory
( cd readump ) and entering the command

	        make 

The available makefile options will listed in menu form

	Please choose the appropriate make option,
	then type 'make OPTION' (e.g. make SGIF)

	 DECC    compile C programs (DEC Alpha machine)	 
	 HPC     compile C programs (HP machine)
	 SGIC    compile C programs (SGI machine)
	 SUNC    compile C programs (SUN machine)
	 LNXC    compile C programs (Linux machine)
	 DECF    compile Fortran programs (DEC Alpha machine)	 
	 HPF     compile Fortran programs (HP machine)
	 SGIF    compile Fortran programs (SGI machine)
	 SUNF    compile Fortran programs (SUN machine)

 
A user with an SGI computer wanting to compile the C programs would use the 
following command

	        make SGIC


A user with an SGI computer wanting to compile the Fortran  programs would use
the following command

	        make SGIF


*Note: the UNIX systems used must have an ANSI compatible C compiler
     
The C compiler will create the following files within the bin directory

	readump/bin/read_haloe_l2

The Fortran compiler will create the following files within the bin directory

	readump/bin/READUMP_HALOE_L2

After successfully installing the software, you may want to insert the bin 
directory in your UNIX path.  Since each system is very different, consult 
your system administrator for instructions.
