========

If you want to browse your CGNS file, just type::

  CGNS.NAV

and the pyCGNS browser appears.

   :width: 26cm

The file format is detected using the file extension. You can give a list
of files to ``CGNS.NAV``, it opens each file w.r.t. its type.
The ``.cgns`` extension uses the CGNS library which can detect both
CGNS/ADF and CGNS/HDF formats::

  CGNS.NAV wing.cgns plane.adf helicopter.hdf cror.py

It can load/save CGNS files with
the HDF5/ADF and Python formats, parse and display the contents,
edit the contents using simple edit and copy/paste commands, select
nodes using complex queries, use already defined patterns such as the *SIDS*
patterns and other interoperability features.

   There are a *lot* of screenshots in this ``CGNS.NAV`` doc, some may
   be a bit out-dated but most of the look-and-feel of the tool would
   keep unchanged.
