SYNOPSIS

gri [ 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 capabilities (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.

The info manual is normally accessed by typing

info gri

The html manual is located at /usr/doc/gri-N.N.N/html/index.html, where N.N.N is the version number.

The html FAQ is located at /usr/doc/gri-N.N.N/html/FAQ.html

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
