Thanks for sending this, it looks quite useful.  I'm CC:ing Glenn Davis
and Steve Emmerson also, in case they have comments.  I notice that you
used netCDF 3.3.1 as a code base.  Would it be practical to integrate
your changes into the latest 3.4 release instead, so users could have
the latest bug fixes and performance improvements?  I know this might be
a *lot* of work, ...
