I installed "GRASS6.4.svn" and I tried "v.label.sa". I see that this
tool mantain the number of labels, and re-arrange labels locations for
better results. But my map has many elements. It is necessary to
suppress some labels, or some points.

For example, I have seen that the program MapServer performs this task
very well.

Anyway, I'm very happy using GRASS! So, thanks all. Specially, to developers.
