 I'm stymied trying to get output from r.param.scale that is equivalent to
the example on the bottom of the man page.

  Resetting g.region to the input elevation map without any additional
options and adding a zmult factor of 5 appears to help. When the specified
param is 'features' I see what should be ridges and channels, but no peaks
or pits.

  Changing the calculated param to either elev or profc yields blank maps
when I try to display them with d.rast.

  Suggestions on how to properly apply this module will be very helpful.
