Where do I get a ppm driver?

[Linda Moet]

Thanks for your quick reply.  After I posted my question, I found the
command that does what I need:

    r.out.ppm input=raster_file output=ppm_file

No ppm driver required.  I don't know how I missed it when I was surfing
through the manual pages.  =+\

Best regards,
