+SUMMARY="A graphics programming language."
+DESCRIPTION="Gri is a language for scientific graphics programming. The word
+'language' is important: Gri is command-driven, not point/click. Gri can make
+x-y graphs, contour graphs, and image graphs, in PostScript and (someday) SVG
+formats. Control is provided over all aspects of drawing, e.g. line widths,
+colors, and fonts. A TeX-like syntax provides common mathematical symbols."
