+Description:
+  GMT is an open-source collection of command-line tools for manipulating
+  geographic and Cartesian data sets (including filtering, trend fitting,
+  gridding, projecting, etc.) and producing high-quality illustrations ranging
+  from simple x–y plots via contour maps to artificially illuminated surfaces
+  and 3D perspective views. It supports many map projections and transformations
+  and includes supporting data such as coastlines, rivers, and political
+  boundaries and optionally country polygons.
