description         The Generic Mapping Tools
long_description GMT is an open source collection of ~120 tools \
    for manipulating geographic and Cartesian data sets and     \
    producing PostScript illustrations ranging from simple x-y  \
    plots via contour maps to artificially illuminated surfaces \
    and 3D perspective views.
