Andrew,

Here's what I have done in the past:

  1. Use s.in.ascii to convert the attributes file for the generated
     contours into a site list.  Typically it would be something like:

        cd $LOCATION/dig_att
        awk '/^L/ { print $2, $3, $4; } contours | s.in.ascii site=contour_labe
l

  2. Use s.label to convert the sites into labels.

  3. Use d.labels to move badly placed labels and remove extra labels.
     I don't have a lot of luck with d.labels, so I edit the label
     file directly more often than not.

There can sometimes be a lot of manual labor involved, and the results
are typically not very pretty, but it works.

Hope this helps.

Bill.
