**How to install?**

It is assumed you were able to compile successfully the `mcd` sources with `gfortran`.

The `netCDF` library should be installed on your system. 
Moreover, from our experience, it seems that it must have been build
using the `-fPIC` (for `gfortran`; the name of the option changes with compilers) 
option which generates position independent code suitable for use in a shared library.
An example script is given in the `netcdf` folder.

The installation below relies on `f2py` utility, which is part of the `numpy` package.

1. Getting the environment variables right: add the `mcd-python` folder to `PYTHONPATH` in your environment file (e.g. `.bashrc`)

export PYTHONPATH=$PYTHONPATH:adapt_to_your_own/mcd-python

2. Modify the compile script `compile_fmcd.sh` to link your local `netCDF` libraries and `mcd` distribution (Fortran sources)

3. Check that `f2py` is included in your `python` library suite.

4. Run `compile_fmcd.sh` and check for the created `.so` file (its size should be about 1 Mo)

**Quick test**

quicktest.py

Next step is to try and learn about the use of `mcd` Python library with the `tutorial` folder.

A more advanced example (direct use of `fmcd` compiled with `f2py`) is provided in the `test_mcd` folder.

**Python 3**

*Solution suggested by Aaron Berliner*

This can be done using the 2to3 package and the reindent

Run 2to3 -v -n -W -f all mcd.py
    Run 2to3 -v -n -W -f all mcdcomp.py
    Run reindent mcd.py
    Run reindent mcdcomp.py

Then upgrade to the appropriate basemap in python3.
