+ Notes on .JAW files:
+   This is a file format created by Jawed Karim for Jaw3D
+     (http://jaw3d.home.ml.org).
+          -- updated 11/6/00 - www.jawed.com
+   It is very simple, and lets one easily create ones own models using only
+   a text editor. The format is pretty simple:
+     The first line must be "Light: (x,y,z)" where x,y, and z are the x y and
+        z components of the lightsource vector (I think ;)
+     A series of lines, numbered 0 to n, in the format of
+        "i: x y z", where i is the vertex number (which should be listed in
+        order, and x y and z are the coordinates of that vertex.
+     A series of lines, having the format "tri a, b, c" where a b and c are
+        the vertices that the face uses. It is unclear at this time which
+        way the vertices are listed (ccw or cw), so just make em consistent
+        and you can always use plFlipObjectNormals() on the loaded object.
+   That is it! (I told ya it was simple).
