+This script imports DEC Object File Format files to Blender.\r
+\r
+The DEC (Digital Equipment Corporation) OFF format is very old and\r
+almost identical to Wavefront's OBJ. I wrote this so I could get my huge\r
+meshes into Moonlight Atelier. (DXF can also be used but the file size\r
+is five times larger than OFF!) Blender/Moonlight users might find this\r
+script to be very useful.\r
+\r
+Usage:<br>\r
+ Execute this script from the "File->Import" menu and choose an OFF file to\r
+open.\r
+\r
+Notes:<br>\r
+ Port to blender 2.5 beta 2. - shuber\r
+ UV Coordinate support has been added. - Scorpius\r
+ FGON support has been added. - Cam\r
+ New Mesh module now used. - Cam\r
