GRI(1)

NAME
gri - scientific graphics language

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; in both cases extensive power rewards tolerance of a modest learning curve. This manpage is for Gri version VERSION.

FULL DOCUMENTATION
This manpage is intended merely as a pointer to the main documentation, which you may find at:

  The INFO manual
is accessed by typing info gri or by accessing the 'info' node in Emacs or in other standard ways.

  The HTML manual
is located at /usr/share/doc/gri-VERSION/html/index.html This manual is very extensive, and one thing you might like to check is the html FAQ associated with the manual, which is located at /usr/share/doc/gri-VERSION/html/FAQ.html

  PostScript reference cards
are at /usr/share/doc/gri-VERSION/refcard.ps (overall reference and quick introduction) and /usr/share/doc/gri-VERSION/cmdrefcard.ps (reference to commands). (Note: users of RedHat versions earlier than 7.0 may find the above-mentioned files in /usr/doc/gri-VERSION instead of /usr/share/doc/gri-VERSION as noted above.)

EMACS SUPPORT
An emacs mode is provided with Gri. It is at /usr/share/emacs/site-lisp/gri-mode.el and is fully described in a chapter in the manual.
