36      <LI>install <A CLASS="la" HREF="http://unidata.github.io/netcdf4-python/">netcdf4</A>, python API interface to netCDF files</LI>
37        <OL>
38          <LI> Some new linux distributions (at least Debian >8) provide the netcdf4 API in the package systems:</LI>
39            <DIV CLASS="codetxt"># apt-get install python-netcdf4</DIV>
40          <LI> Otherwise, it can be manually done. Be careful with interferences with anaconda (some issues on mixture of netcdf libraries have been detected). Make sure, that if you use anaconda, that the netcdf libraries installed are with netcdf4 capabilities.

62     <LI>Now all the scripts are held in ${HOME}/PyNCplot. It might be desirable to set an environment variable to make life easier:
63      <DIV CLASS="codetxt">$ export pyHOME=${HOME}/PyNCplot</DIV>
64      <LI>Finally one need to compile the Fortran modules using the same python to run the scripts. This is done using a standard `Makefile' and the tool <A CLASS="la" HREF="https://docs.scipy.org/doc/numpy-dev/f2py/" TARGET="_blank">f2py</A> to link Fortran compiled codes to python. There are different versions for different LMD/IPSL and French HPC machines. For a standard linux 64-bits machine (debain 7) there is one example as `Makefile.foudre'. Follow the instructions there in after linking the appropriated file:</LI>
65      <DIV CLASS="codetxt">
66      $ ln -s Makefile.[machine].[compiler] ./Makefile
67      </DIV>
68      <LI>In order to create a python 'library' from the fortran codes, one need to follow these steps (example for machine called `foudre')</LI>
