[Pascal Conreaux <stage6@xxxxxxxxxxxxxx>]

Hello everyone,

Netcdf is a good way to store a lot of different data.
But is there a way to specify (or an existing specification to learn)an
user that the Netcdf file describes, in 2D or 3D, 

1)either a structured mesh 
2)or an unstructured mesh

Thanks,
        Pascal.
