Dear GRASS’ers!
I wrote shell script to find “average” line(s) of input vector map.

It works with simple algorithm stated here (with 2 methods – average distance to vectors sampling OR average number of vectors segments).
Results differ depending on vector type: lines/boundaries or polygons. NOTE: Lines/boundaries must have the same direction.
Example picture in includes.

quite nice, thanks. this solves a long-standing problem, for which I never found a
satisfactory solution. very good for averaging multiple GPS tracks of the same road
(I think OSMers will appreciate this).
All the best.

BTW: why not adding it to GRASS trunk?
