# mod 1/07 M. Schwarb (libgrib2c name change)
# mod 4/09 W. Ebisuzaki (use config.h)
# mod 6/10 W. Ebisuzaki ipolates
# mod 8/11 W. Ebisuzaki support environment variable FC={fortran 90+ compiler}
#              needed by optional netcdf4 and ipolates
# mod 3/12 W. Ebisuzaki support openmp, gctpc
# mod 8/12 M. Schwarb  gunzip -n -f,  cd "$var"
# mod 10/12 W. Ebisuzaki
# mod 7/13 W. Ebisuzaki added got netcdf4 working again, added subdirectroy lib, bin, include, man
# mod 11/14 W. Ebisuzaki added target lib, make callable wgrib2
# mod 05/16 G. Schnee add support for template 5.42 compression using libaec

#
#   Configuration
#
# NETCDF3: link in netcdf3 library to write netcdf3 files
#    change: USE_NETCDF3=1 and USE_NETCDF4=0 in configuration below
#
# NETCDF4: link in netcdf4 library to write netcdf3/4 files
#    change: USE_NETCDF3=0 and USE_NETCDF4=1 in configuration below
#    need to download netcdf4 and hdf5 libraries and to put into grib2 directory
#    need fortran90+ compiler (FC)
#
# IPOLATES: link in IPOLATES library to interpolate to new grids
#    USE_IPOLATES=0    do not use the ipolates library, no -new_grid
#    USE_IPOLATES=1    use the grib1 version of ipolates
#    USE_IPOLATES=3    use the double precision grib2 ipolates (beta)
#    need fortran90+ compiler (FC)
#    need to modify makefile and perhaps source code
#    if USE_IPOLATES=3, the fortran compiler needs to have
#     an option to convert reals to double precision
#     gfortran, g95 and intel have it
#
# MAKE_FTN_API: make wgrib2api which allows fortran code to read/write grib2
#    needs fortran2003 or fortran95 with extensions
#
#  MYSQL: link in interface to MySQL to write to mysql database
#    change: USE_MYSQL=1 in configuration below
#    need to have mysql installed
#    may need to modify makefile
#  
#  UDF: add commands for user-defined functions and shell commands
#    change: USE_UDF=1 in configuration below
#
#  REGEX: use regular expression library (POSIX-2), on by default
#    change: USE_REGEX=0 if REGEX library is not available
#     (preferred: get gnu source code to REGEX library)
#
#  TIGGE: ability for TIGGE-like variable names, on by default
#    change: USE_TIGGE=0 to turn off (configuration below)
#
#  USE_PROJ4: the proj4 library is used to confirm that the
#    gctpc code is working right.  
#
#  USE_AEC: enable use of the libaec library for packing with GRIB2 template
#    5.42 (https://gitlab.dkrz.de/k202009/libaec/)
#
#  USE_G2CLIB: include NCEP's g2clib (mainly for testing purposes)
#              USE_G2CLIB = 1, g2clib can be used for decoding by -g2clib 1
#                  requires USE_PNG=1 and USE_JASPER=1
#
#  DISABLE_TIMEZONE: some machines do not support timezones (TZ).
#     if your machine does not support TZ, set DISABLE_TIMEZONE=1
#    this disables the -unix_time option
#
#  DISABLE_ALARM:  some machines do not support alarm(..) (not POSIX-1, IEEE Std 1003.1)
#     use the alarm to terminate wgrib2 after N seconds
#
