+# "Envelope Symmetry" by Jonas Petersen
+# Version 0.9 - 10th November 2004 - first public release

+#
+# A script for creating perfectly symmetrical envelope sets. It is
+# part of the envelope assignment tool.
+#
+# It is available in Object Mode via the menu item:
+#
+#   Object -> Scripts -> Envelope Symmetry
+#
+# With default settings it will:
+#
+# - Look for bones
