All integrable Hamiltonian systems are alike, while each nonintegrable one is nonintegrable in its own way
DESCRIPTION
The sag2grd utility reads a simple ASCII grid (sag) file and writes a number of GMT netCDF (grd) files whose names are the mandatory arguments. The number of grd files is the same as the number of dimensions of the vectors in the sag file.
The program uses the GMT program xyz2grd(1) to perform the gridding of the data, so the GMT toolset must be installed to use this program.
