+This script copies the axis orientation -- X, Y and Z rotations -- of the
+active object to all selected meshes.
+
+It's useful to align the orientations of all meshes of a structure, a human
+skeleton, for example.
+
+Usage:
+
+Select all mesh objects that need to have their orientations changed
+(reminder: keep SHIFT pressed after the first, to add each new one to the
+selection), then select the object whose orientation will be copied from and
+finally run this script to update the angles.
+
+Notes:<br>
+    This script changes mesh data: the vertices are transformed.<br>
+	Before copying the orientation to each object, the script stores its
+transformation matrix.	Then the angles are copied and after that the object's
+vertices are transformed "back" so that they still have the same positions as
+before.  In other words, the rotations are updated, but you won't notice that
+just from looking at the objects.<br>
+	Checking their X, Y and Z rotation values with "Transform Properties" in
+the 3D View's Object menu shows the angles are now the same of the active
+object. Or simply look at the transform manipulator handles in local transform
+orientation.
