This Python implementation of the Thermodynamic Equation of
Seawater 2010 (TEOS-10) is based primarily on numpy ufunc wrappers of
the GSW-C implementation. We expect it to replace the original
`python-gsw <https://github.com/TEOS-10/python-gsw/>`__
pure-python implementation after a brief overlap period.
The primary reasons for this change are that by building on the
C implementation we reduce code duplication and we gain an immediate
update to the 75-term equation. Additional benefits include a
major increase in speed, a reduction in memory usage, and the
inclusion of more functions. The penalty is that a C (or MSVC C++ for
Windows) compiler is required to build the package from source.

**Warning: this is for Python >=3.5 only.**

**Warning:** the only *official* TEOS-10 implementations are
provided as zipfiles at <http://www.teos-10.org/software.htm>.

Documentation is provided at <https://teos-10.github.io/GSW-Python/>.

For the core functionality, we use an auto-generated C extension
module to wrap the C functions as numpy
`ufuncs <https://docs.scipy.org/doc/numpy/reference/ufuncs.html>`__,
and then use an
autogenerated Python module to add docstrings and handle masked
arrays. 165 scalar C functions with only double-precision
arguments and return values are wrapped as ufuncs, and 158 of
these are exposed in the ``gsw`` namespace with an additional
wrapper in Python.

A hand-written wrapper is used for one C function, and others
are re-implemented directly in Python instead of being wrapped.
Additional functions present in GSW-Matlab but not in GSW-C may
be re-implemented in Python, but there is no expectation that
all such functions will be provided.

The package can be installed from a clone of the repo using
``pip install .``. It is neither necessary nor recommended
to run the code generators, and no instructions are provided
for them; their output is
included in the repo. You will need a suitable compiler: gcc or
clang for unix-like systems, or the MSVC compiler set used for Python
itself on Windows. For Windows, some of the source code has been
modified to C++ because the MSVC C compiler does not support the
C99 complex data type used in original GSW-C.

To test, after installation, run "py.test" from the source directory.
