[netCDF #RMF-313749]: related to projection library in netcdf-4

Ghansham,

> What about C/C++/fortran libraries?

No, there is no support for projections or a grid_mapping attribute in
the netCDF C-based libraries, including the C++ or Fortran libraries.

The CF Conventions are not part of the netCDF C/C++ libraries from 
Unidata, although we recommend use of those conventions.  In addition
to the netCDF-Java support for CF Conventions, there is a Python library
from the UK that provides some support for CF conventions:
