4.3: Viewing Gri OutputGri does not draw directly on your screen. Instead, it creates a PostScript file, assuming that you know how to view or print such a file. If you don't have a PostScript previewer, you might want to get the Free Software Foundation's `Ghostscript ' (or ```gs ''')
program, which works very well.
On a unix system, you may invoke both Gri and the previewer on the same
commandline, e.g., `gri foo.gri && gs foo.ps ' (many users create a
shellscript that does this).
Gri PostScript output is standard, and can be viewed with standard
viewers such as `ghostview ' or `gv '.
4.4: Printing Gri OutputGri output files are in the PostScript page description language.
