Jan 24, 2007 W/NP11:SAG W3lib Library. This library contains Fortran 90 decoder/encoder routines for GRIB edition 1, general date manipulation routines, and a Fortran 90 interface to "C" language I/O routines. The user API for the GRIB1 routines is described in file "grib1.doc". Some Fortran routines call "C" functions, which must follow a specific symbol naming convention used by your machine/loader to be linked successfully. If you are having trouble linking to the routines in this library, please make sure the appropriate machine is defined as an option in the CFLAGS variable in the Makefile. See the first few lines of the Makefile for valid options. Recompile the library.
