+This script exports a Mesh to a RAW triangle format file.
+
+The raw triangle format is very simple; it has no verts or faces lists.
+It's just a simple ascii text file with the vertices of each triangle
+listed on each line. In addition, also quads can be exported as a line
+of 12 values (this was the default before blender 2.5). Now default
+settings will triangulate the mesh.
+
+Usage:<br>
+ Execute this script from the "File->Export" menu. You can select
+whether modifiers should be applied and if the mesh is triangulated.
