Am I right in stating that ppm is not the ideal format to use as standard 
input (or output) from GRASS, even when it's PD? To my experience ppm 
files become very large and pbmplus is definitely slower than for 
example xv or Image Alchemy - maybe that's not an issue for everyone, but 
on my Sun IPC I don't want to spend much CPU and disk space on converting 
images. The real problem with pbmplus seems that it uses ppm,pgm and pbm as 
an intermediate format for every conversion, whereas e.g. Image Alchemy 
(at least that's what it seems to do) converts directly from one format 
to the other. But I totally agree with Darrell that it's completely 
useless to write conversion routines for GRASS where there are several 
packages around that do that kind of stuff; maybe we should try to 
convince the authors of the other packages to include an export option to 
GRASS.
