+This script imports Raw Triangle File format files to Blender.
+
+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, a line with 12 values will be
+imported as a quad. This may be in conflict with some other
+applications, which use a raw format, but this is how it was
+implemented back in blender 2.42.
+
+Usage:
+Execute this script from the "File->Import" menu and choose a Raw file to
+open.
+
+Notes:
+Generates the standard verts and faces lists, but without duplicate
+verts. Only *exact* duplicates are removed, there is no way to specify a
+tolerance.
