Thanks for reporting the bug.  We'll put in a fix.

We plan to enhance and support it.  The version we release will have
package and method name and access changes, however, so be prepared for
such changes before you write a lot of code to the current interfaces.

Joe is here visiting today and I've just gone through a walk-through, so
I have a good idea of what we will be doing next:

  - Adding an attribute class to the netcdf package
  - Adding create and write methods to the netcdf package
  - Adapting the rmicdf classes to Sun's Alpha 2 release of RMI (almost
    done)
  - Changing the access of many fields and member functions from public
    to private or "phriendly"
  - Adding more documentation for javadoc
  - ...

I can't say when we'll have a version to release, but I'm hoping it won't
be too long.
