      Ghostscript is the name of a set of tools that provides (i) an
      interpreter for the PostScript language and the PDF file format,
      (ii) a set of C procedures (the Ghostscript library) that
      implement the graphics capabilities that appear as primitive
      operations in the PostScript language, and (iii) a wide variety
      of output drivers for various file formats and printers.
