SUMMARY = "The GPL Ghostscript PostScript/PDF interpreter"
DESCRIPTION = "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. \
\
Furthermore, it can render PostScript and PDF files as graphics to be printed \
on non-PostScript printers. Supported printers include common \
dot-matrix, inkjet and laser models. \
\
Package gsfonts contains a set of standard fonts for Ghostscript. \
