+# - added 'comment' prefix to comments - Needed to comply with the PLY spec.
+#
+# Updated on Jan 1, 2007 by Gabe Ghearing
+# - fixed normals so they are correctly smooth/flat
+# - fixed crash when the model doesn't have uv coords or vertex colors
+# - fixed crash when the model has vertex colors but doesn't have uv coords
+# - changed float32 to float and uint8 to uchar for compatibility
+# Errata/Notes as of Jan 1, 2007
+# - script exports texture coords if they exist even if TexFace isn't
selected (not a big deal to me)
+# - ST(R) should probably be renamed UV(T) like in most PLY files (importer
needs to be updated to take either)
+#
+# Updated on Jan 3, 2007 by Gabe Ghearing
+# - fixed "sticky" vertex UV exporting
