[GRASSLIST:5236] vector question

[Ivan Marchesini]

Hello to all

have you idea how I can do a unusual thing with grass???
I would like to draw a vector polyline (not straigth) using v.digit and then 
to obtain some straigth line, regulary spaced, perpendicular to the 
polyline..... like this:           --|----|----|----|----|-- 
the problem is that I need a large number of these perpendiculars and I would 
like to obtain them automatically after drawed the polyline......   :-)

I know it is a unusual question but I hope someone can help me......
thank you....

Bye Ivan
