%description
The NCEPLIBS-g2 library contains Fortran code to read and write GRIB edition 2 files,
and utilities to manipulate GRIB2 files.
GRIdded Binary or General Regularly-distributed Information in Binary form (GRIB)
is a data format for meteorological and forecast data, standardized by the
World Meteorological Organization (WMO). GRIB edition 2 (GRIB2) was approved by
the WMO is 2003.
