> 
>     The tokens NCCLOB and NCNOCLOB changed from netCDF2 to netCDF3
> 
> As a result, our libraries which provide an AQM-oriented API on top
> of netCDF no longer work.  Why this gratuitous change?

>     It is not necessary to rewrite programs that use the

>     includes a backward compatibility interface that supports
