the program will know the types of geometry you are working with in
the file, based upon the type you digitize into it.

if you use v.digit and add "lines", it will be aware of lines and
report them with v.info or after it is built for topology when exiting

If you add boundaries, it will expect a centroid to be in the
boundary, and the boundary to be closed. It turns green when it is

when you have a boundary and a centroid, and it exits/builds, it will
report the areas, which will be your polygons.
