r.in.sunrast

[Brian J. Scamman]

Hi,
I've been trying to convert a sunraster image into the grass format.  The
conversion seems to go ok (I'm using the 4.0 updated version of r.in.sunrast)
but when I display the image using d.rast, the image is all white.  The 
documentation for r.in.sunrast mentions using r.support, but there is no 
documentation for r.support.

If anybody could tell me what step I'm missing, I would appreciate it.

Thanks,
Brian
