     NAME
          dxf2rib - convert AutoCAD R10/R11 DXF files to Pixar
          RenderMan Bitstream Interface

     SYNOPSIS
          dxf2rib [-hVcsp][-v n][-R n][-t n][-m n][file]

     DESCRIPTION
          dxf2rib convert 3D ASCII DXF data files to ASCII RIB files

          dxf2rib understands the following primitives:

               - LINE

               - POINT

               - CIRCLE

               - ARC

               - TRACE

               - SOLID

               - BLOCK

               - ENDBLK

               - INSERT

               - POLYLINE

               - VERTEX

               -         3DPolyline

               -         3DPolygMesh

               - SEQEND

               - 3DLINE

               - 3DFACE

          The following primitives are currently ignored:

               - TEXT

               - SHAPE

               - ATTDEF

     OPTIONS
          dxf2rib

          -h:  Print Help and exit

          -V:  Version

          -c:  To stdout

          -s:  Make not-structured RIB

          This means not to print structural comments

          -v #:
               Set verbose level to #:

               1: Print Debug info too

               2: Print Info too (default)

               5: Print Warnings too

          -R f:
               Use f(float) as radius in LINES

          -t #:
               Convert four-sided-polygons to:

               0: Four-sided-polygons (default)

               1: Two triangles

               2: Bilinear patch

          -p:  Generate normals for poly*meshes

          -S file:
               Use file for set shaders for LAYERS

          The file has the following format:

                ----------------------

          -M #:
               Allocate memory for # 3D vertex (default 256)

          -B #:
               Allocate memory for # Blocks (default 256)

          file:
               If omited, translate standard input to standard output
               Otherwise, file must be *.dxf or *.DXF; output files
               will be *.rib.  There is not warning if *.rib exists

     RETURN VALUE
          dxf2rib 0 if no error.  1, -1 or errno otherwise.

     EXAMPLES
          dxf2rib Translate a compressed dxf to a compressed rib:

               zcat foo.dxf | dxf2rib | compress -c > foo.rib.Z

          Create a dummy file for shader from a dxf
