README.unpacking

uvspec is part of the libRadtran package which is available from

    http://www.libradtran.org

To unpack libRadtran issue the following commands on a unix system:

    gzip -d libRadtran-latest-version-number.tar.gz
    tar -xvf libRadtran-latest-version-number.tar

Next 

    cd libRadtran-latest-version-number

and follow the instructions in the README and INSTALL files.

Documentation is found in the doc directory.

uvspec uses both C and Fortran code. Hence, to compile and link uvspec
a Fortran compiler that is compatible with C is needed. The configure 
script will find out whether your system's Fortran and C compilers are
compatible.

After a succesful build the uvspec executable is found in the bin 
directory. libRadtran is currently being developed on both Linux and
Max OSX systems.
