I have a program that you can read just parts of a netCDF file, since
that is usually what I have to do. This works like:

IDL> im = tx_nc_getdata(sample_filename, '/image')

or even,

IDL> plot, tx_nc_getdata(sample_filename, '/image[*, 256]')

You can read attributes too:

title = tx_nc_getdata(sample_filename, '/image.TITLE')

I have a TX_NC_DUMP routine that prints a listing of the contents of a
file and a TX_NC_BROWSER that is like H5_BROWSER.
