[GRASSLIST:709] Contours' labels

Hi again folks,

New question.  I have these contour lines that I am not sure are labelled.
These were transferred over from a .dxf file.  I used v.in.dxf to extract
the layers.  There were the tree contour layers and a label layer.  Used
v.patch to couple combine the three layers and the label layer.  Then I ran
v.support on the resultant map.  I ran v.llabel on the file, thinking it
would take the label layer and attach the labels to the contours.  I made a
raster file out of this vector map using v.surf.rst.  When I ran r.color to
set the colours for the elevations, then displayed the map, the colours
didn't come out as they should have.  I am concluding that v.llabel does not
work as I though it did.  If one extracts contours and their labels from a
dxf file, how does one ensure that the labels (i.e. 100 200 300 ... Metres)
will attach to their respective contours.

At present this is the only thing holding me up.  Any help will be, as
always, greatly appreciated.
