We check for netcdf files like this:

header = bytarr(3)
openr, lun, filename, /get_lun
readu, lun, header
free_lun, lun
if string(header) eq 'CDF' then print, 'I think this might be a netcdf file...'

This is based on the file format specs from Unidata
( http://www.unidata.ucar.edu/packages/netcdf/guidec/guidec-18 .html)
