 > > This raises the question of whether it would be envisageable /
 desirable to add an option to v.net allowing to create nodes _on_ the
 existing network when connecting new points, instead of connecting these
 points by short lines. IOW, instead of currently adding a short line from
 any point in the given threshold to the network, "just" create a new node
 on a point of the network that is closest to the point you wish to add. Am
 I being clear ? ;-)

 points to network". I think this makes sense for network preparation in
 general, particularly for features like schools, hospitals etc. that are
 represented by a point.

 Thanks a lot, this is perfect ! I added a note to the man page about this
 flag.
