[GRASS-user] to shorten lines

[ivan marchesini]

Dear Users...
I have a vector lines map...
I would like to shorten each line of the map.... the amount of the
shortening could be fixed (10 meters.. may be)
I would like to do this in each part of the line...  i.e.:

old lines:
____________

new lines:
 __________


any idea about a quick way to solve this problem...???

thanks...

Ivan
