+#and "#Type:" follwed by "edge_specified" or "face-specified"
+#if edge_specified is given, then faces cannot be drawn,
+#if face_specified is given then faces and edges can be drawn
+
+#Vertices are given as "v" followed by three numbers (x,y,z).
+#All files need a vertex list
+#v x.xxx y.yyy z.zzz
+
+#Faces are given by a list of vertices
+#(vertex 1 is the first in the list above, 2 the second, etc):
+#f 1 2 3
+
+#Edges are given by a list of vertices. These will be broken down
+#into adjacent pairs. Each edge can connect only two vertices
+#l 1 2 3
+
+#Faces are rendered according to the painter's algorithm and perhaps
+#back-face culling, if selected. The parameter to sort the faces by
+#is user-selectable
