 Ghostscript is used for PostScript/PDF preview and printing. Usually as
 a back-end to a program such as ghostview, it can display PostScript and PDF
 documents in an X11 environment.
 .
 The Ghostscript home page is at http://www.ghostscript.com/
 .
 This package contains the Ghostscript output device for X11. It is in
 a separate package to allow the main package (ghostscript) to be installed
 on X-less servers.
