To make the gribw library, type

      make -f gribwlib.make

   Then go to the directory tools and take a look at
the example program:

      gribify_nmc0.*


Gribw(riter) status:

   You are getting a snapshot of my working directory
and it contains much old code.  Much of the old code
is for earlier verions of gribw.  For examples of
code using the current API, look at examples and tools.

   To determine the current API, consult pdstool.h,
gdstool.h, gribwlib.h and gribw_time.h

   The API for grib reading is very primative and
insufficient for much useful work.  Routines for
determining the contents of a grib message need to
be written.

   A second API was suggested by a Canadian and 
equivalences a structure with the pds & gds.  More
useful in reading GRIB data.
