GRI(1)GRI(1)NAMEgri - scientific graphics language
SYNOPSISgri [ OPTIONS ] [ CommandFile [ optional_arguments ]]
DESCRIPTION
Gri is a programming language for scientific graphics. It can make x-y
graphs, contour-graphs, and image graphs. In addition, Gri has a full
suite of low-level graphical elements and sufficient programming capa‐
bilities (loops, subroutines, etc) to permit complex customization.
Gri is not a point-click application. In some ways it is analogous to
TeX. Extensive power rewards tolerance of a modest learning curve.
For more information, please consult online info and html manuals.

GRI_MERGE AND GRI_UNPAGE COMMANDS
Two Perl scripts are provided with Gri to manipulate the PostScript
output.
gri_merge is used to merge multiple Gri output files into a single
PostScript file. Type gri_merge -h for usage information.
gri_unpage is used is split a multi-page Gri output file (in which the
new page command was used) into separate PostScript files, one for each
page. Type gri_unpage -h
EMACS SUPPORT
An emacs mode is provided with Gri.
The mode is installed automatically in Debian by the elisp file:
/etc/emacs/site-start.d/50gri.el
The emacs mode itself is gri-mode.el and is installed on Debian as
/usr/share/emacs/site-lisp/gri-mode.el
Byte-compiled versions of this file are produced for every flavour of
Emacs that is installed, and are located in places like
/usr/share/emacs/20.2/site-lisp/gri-mode.elc
