+// DragDropExtra Scriptaculous Enhancement, version 0.5
+// (c) 2007-2008 Christopher Williams, Iterative Designs
+//
+// v0.5 release
+// - Fixed bug where 2nd drag on an element in IE would result in funny placement of the
+// element. [shammond42]
+// v0.4 release
+// - Fixed issue with dragging and dropping in IE7 due to an exception being thrown and not properly reseting in FinishDrag.
+// v0.3 release
+// - Fixed bug found by Phillip Sauerbeck psauerbeck@gmail. Tests added based on Phillip's efforts.
+// v0.2 release
+// - Minor bug fix for the releasing of objects after they have been dropped, prevents memory leak.
+// v0.1 release
+// - initial release for the super ghosting capability
+// - Drags from one scrolling list to the other (overflow:auto)
+// - Retains the original object so that it can remain present despite being dragged
+//
+// dragdropextra.js is freely distributable under the terms of an MIT-style license.
+// For details, see the Iterative Designs web site: http://www.iterativedesigns.com/
