unknown vector format

Hi list,

I have a vector ascii file (*.pol) with the
following format:

         1 25.739523 70.986565

         25.551941 70.923874

         25.538887 70.926102

         25.527222 70.929718

         25.518330 70.933884

         25.499723 70.946930

         25.496109 70.951660
etc

END

         2 25.554712 69.857948

         21.491795 70.224655

         21.525814 70.256569

         21.578819 70.316658

         21.578819 70.316658

         21.583054 70.314987
etc

Does anybody know what soft could this come from and
how to import it to grass?
I've tried v.in.arc:

v.in.arc -n type=pol lines_in=VGEUGG.POL vector_out=test

but get a little line out of a 17569805 bytes *.pol file

Thanks
