ghostscript-x 8.64.dfsg.1-0ubuntu15 (amd64 binary) in ubuntu karmic

 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.

 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.
