At the moment, this package contains the programs psmegaplot which you can use to make large posters using a simple laserwriter, makepattern which generates raster patterns from GMT 3.0 icon files, gmtdigitize which provides a GMT interface to a digitizing tablet via a serial port, gmtstitch which can be used to assemble pieces digitized lines into complete lines or polygons, gmtdp which performs line reduction using the Douglas-Peucker algorithm, and nc2xy which can extract data from column-oriented netCDF files. The package is maintained by Paul Wessel. The increasingly popular utility ps2raster, which simplifies the rasterization of GMT PostScript to raster formats (see Appendix C), was moved to the general tools starting with GMT 4.2.0.
