[Gdal-dev] converting lines to polygones with ogr

[C.Strobl at dlr.de]

hi all,
 
is there a possibility to convert with ogr lines to polygones, for example like
 
ogr2ogr -f  "ESRI Shapefile" -nlt POLYGON c:\home\dat_poly.shp c:\home\dat_line.shp
 
or does somebody know another open source solution for this task.
 
thanks for your help and greetings from munich
