[Qgis-user] lines with arrowheads

[M S]

One of the outputs from r.flow in GRASS is downslope flow lines.  Without
arrowheads (or some similar symbol like that) at the end of lines pointing
which way is downhill, the lines become ambiguous.

Is there a way to draw these lines with arrowheads?   Or some other approach
that might achieve this?
