Package gri-2.12.23-2

Gri is a language for scientific graphics programming. The word "language" is important: Gri is command-driven, not point/click. Some users consider Gri similar to LaTeX, since both provide extensive power as a reward for tolerating a learning curve. 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. Folks who write thousand-line Gri scripts usually start with something as simple as the following, which produces an auto-scaled graph. open file.dat read columns x y draw curve
