DESCRIPTION

       v.lrs.label generates LRS labels for pretty-printing of a LRS.  This  example  is  written
       for the Spearfish dataset (it continues the example from v.lrs.create).

       v.lrs.label route_lrs rstable=route_lrs output=route_lrs_labels \
                   labels=labels col=red size=50 xoffset=100
       g.region vect=route_lrs n=n+100 s=s-100 -p
       d.erase
       d.vect route_lrs
       d.vect route_lrs_labels col=grey type=line
       d.vect busstops disp=attr attr=cat size=10 bg=white lcol=green yref=bottom
       d.vect busstops icon=basic/circle fcol=green
       d.labels labels
