There isn't currently an efficient way to join slices either using
commands or the public C API.
I wonder if the segment lib could be (ab)used for

Hi List --
Looking at function centroid() in geom.c
of v.in.ogr, it seems to me that the code
for import of polygons always assumes that
the first ring is the exterior boundary and
the following ones are all interior
in GRASS 6 to complete in 10 minutes instead
of 16+ hours, but I am not sure if this fix can/will go into GRASS 6.4
because by now only bugs should be fixed.

Here's the parameters reported by v.kernel as it's executing:

The documentation is correct. The problem arose because
((A/100)/(1-(A/100)) returns an integer value if A is an integer, i.e.
the truncation happened before log() is called.
