 Gibbs SeaWater (GSW) Oceanographic Toolbox of TEOS-10 (Fortran)
==========================================================================

 This is a subset of functions contained in the Gibbs SeaWater (GSW)
 Oceanographic Toolbox of TEOS-10.

 Version 1.0 written by David Jackett
 Modified by Paul Barker (version 3.02)

 For help with this Oceanographic Toolbox email: help@teos-10.org

 This software is available from http://www.teos-10.org

==========================================================================

 gsw_data_v3_0.nc
 NetCDF file that contains the global data set of Absolute Salinity Anomaly
 Ratio, the global data set of Absolute Salinity Anomaly atlas, and check
 values and computation accuracy values for use in gsw_check_function.
 The data set gsw_data_v3_0.nc must not be tampered with.

 gsw_check_function.f90
 Contains the check functions. We suggest that after downloading, unzipping
 and installing the toolbox the user runs this program to ensure that the
 toolbox is installed correctly and there are no conflicts. This toolbox has
 been tested to compile and run with gfortran.

==========================================================================

 Build using Make:
 cd test
 make
 ./gsw_check
 ./poly_check

==========================================================================

 Build using CMake:
   static and shared libraries
   build 'gsw_check_functions' and 'gsw_poly_check' on demand
   provides a package configuration
   Git submodules support
   Window (Visual Studio), Mac and Linux support

 Windows (using a terminal):
   mkdir build; cd build
   cmake ..
   Open gsw.sln in Visual Studio

 Mac, Linux:
   mkdir build; cd build
   cmake ..
   make
   ctest

 Use a Git submodule (using extern/gsw as target folder):
   git submodule add https://github.com/TEOS-10/GSW-Fortran extern/gsw
   git submodule init
   git submodule update
    ... add e.g. target_link_libraries(my_target STATIC gsw_static)
    ... in your CMakeLists.txt. It is not necessary to compile and install
    ... the TEOS-10/GSW library - the compilation and linking will be done
    ... due to the target_link_libraries() statement.

 Note that gfortran is the name of the GNU Fortran project, developing a
 free Fortran 95/2003/2008 compiler for GCC, the GNU Compiler Collection.
 It is available from http://gcc.gnu.org/fortran/
