Hi Antero,

thanks for your review! Here's an updated version of the patch. I added
--with-netcdf to the configure flags, removed the build utils, added
spaces between sentences and don't use a list for the licence field
anymore.

Could you have another look please?

I'm not sure if I addressed all lint issues, since this command is
failing on my machine recently. Any idea what this could be? Here's the
backtrace of the lint command:

```
