DESCRIPTION
v.label.sa makes a label-file from a GRASS vector map
with labels created from attributes in the attached table. The labels are
placed in as optimal place as possible. The label file has the same syntax
as the one created by v.label
EXAMPLE
Spearfish example:
d.font -L
v.label.sa roads font=/usr/share/fonts/TTF/Vera.ttf labels=roads_labels col=label
g.region vect=roads
d.erase
d.vect roads
d.labels roads_labels
