 +====== Extended Wavefront OBJ format ======
 +
 +===== About =====
 +
 +Obj is a simple 3d file format.
 +Antiryad Gx importer and exporter use extended format when importing and exporting Wavefront OBJ files to break some limitations.\\
 +Some new specifications are based on adoptions found on other softwares.
