[Pkg-grass-general] BNA file import to QGis?

[ralf@skolelinux.de]

Dear GIS users and developers,

ten years ago I made some maps using a proprietary software called Goldensoft Mapview IIRC. 
There, I could interchange boundary data (polygons) in an ascii format
as shown below (extension had been BNA). As I like the idea to re-use
this data with QGis, I wonder what was the easiest way to import my
files?

Is this format still in use, so we should go for an appropriate import
filter?

Thanks to you all,
Ralf (Bielefeld, teaching geography, maths, computing)

P.S.: Now, this is the way those files look like:
Each object starts with a base line defining its ID, description and the
amount N of succeeding lines (= coordinates). IIRC one could distinguish
areas from linear objects by switching the signum of N.

Now, here we go (cut fraction):
