[netCDFPerl #BVM-455008]: Validating with Perl NetCDF

["Unidata netCDF Perl Support" <support-netcdf-perl@xxxxxxxxxxxxxxxx>]

The NetCDF-Perl package doesn't have anything equivalent to the is_valid() 
method.

I think you could modify the "ncopts" variable so that the open() doesn't die 
but, instead, returns an error code.  It would then be a matter of writing a 
Perl subroutine that tested the file for validity by performing the same steps 
as the is_valid() function.

It seems, however, that it would be simpler to write C++ program to do the 
validating rather than a NetCDF-Perl script.
