The gridlink.py script creates three separate databases and makes
some links between them. You may use the parser tool to have a look at
the result trees. This very simple demo aims at being extended. So far, we
can create links with the ADF layer, but this requires a open/close
on the CGNS database on which you are working with the mid-level library.

The hydro.py also is an example of link use.
