Hey - me too! Except rather than write a conversion program each time, I just pipe the
hdfdump[*] utility output into the ncgen utility to convert files I use. E.g.

hdfdump <hdfile> | ncgen -b <ncfile>

and I end up with a nice simple, useful netCDF file. :o)

[*] Earlier HDF libraries called this "ncdump" which was very annoying.
