GRI(1)                 DragonFly General Commands Manual                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.  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
