netcdf.f90 contains the "netcdf" module for use with Fortran-90. The module may be used instead of including "netcdf.inc". The module defines relevant constants and provides interface blocks for some (but not all) of the library functions and subroutines. The contibutors are Russ Rew at Unidata (russ@unidata.ucar.edu) and Robert Pincus (Robert.Pincus@gsfc.nasa.gov).
