r.out.ppm3 help
r.out.ppm3 [-qc] red=string green=string blue=string output=string 
Flags:
- -q
 - Run quietly

Parameters:
- red=string
 - Name of raster map to be used for

DESCRIPTION
r.out.ppm3 converts 3 GRASS raster layers (R,G,B) to a PPM
image file, using the current region.
This program converts a GRASS raster file to a PPM image file
using the the current region settings.
To get the full area and resolutin of the raster map, run:
    g.region rast=[mapname]
before running r.out.ppm3.
NOTES
One pixel is written for each cell value, so if ew_res and ns_res
differ, the aspect ratio of the resulting image will be off.
