+#    - 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
+#    - added pupmenu to enable/disable exporting normals, uv coords, and colors
+# Errata/Notes as of Jan 3, 2007
+#    - ST(R) coords should probably be renamed UV(T) like in most PLY files (importer needs to be updated to take either)
+#    - edges should be exported since PLY files support them
