DESCRIPTION

       Standard DXF is imported. The following graphical objects are supported:

                     GRASS point type:
       DXF POINT

                     GRASS line type:
       DXF LINE DXF POLYLINE DXF LWPOLYLINE DXF ARC DXF CIRCLE DXF TEXT

                     GRASS face type:
       DXF POLYFACE MESHES DXF 3DFACE
       Capital column names  are  changed  to  lowercase  characters  as  for  easier  SQL  usage
       (lowercase column names avoid the need to quote them if the attribute table is stored in a
       SQL DBMS such as PostgreSQL).
