GRASS TIFF or GIFF import /export files

[Precision Farming Project]

Hi,

I'm looking for the location (ftp site and path) for r.in.tiff, r.in.gif 
and r.in.ppm routines in order to "load" scanned aerial photographs into 
Grass4.1.

I checked out the moon site under the /pub/grass/outgoing/Raster 
directory to find the above mentioned r routines/commands with no luck.  

Any suggestions and or assistance would be most appreciated.

Thanks,
