[GRASS-user] Shape lines to GRASS area (boundary + centroid), 101

Hi,
I am stuck with the olde issue about to create both vector boundaries and vector centroids out of a shape file consisting of lines.

The lines have been imported (v.in.ogr), cleaned (v.clean) and v.type was used to produce boundaries
v.type input=shapefile output=foo type=line,boundary.

What is the missing step to _automatically_ produce centroids ? I am dealing with a ton of administrative boundaries which prohibts digitizing by hand.

v.centroids ?
(which actually just a frontend to v.category)
