Can you point me to this resource? (if other than both v.in.ogr and
v.cleanman pages)
I would really appreciate to do further reading on this as often shape files
comes from arcgis (quite always in my case) and some "massaging" must be
done in order to get them properly usable with grass.

Should all these affect the patching of v.clean(ed) shapes and subsequent
missing areas in the result?
