+<!--
+ This file demonstrates how the dojox.wire code can be used to do declarative
+ wiring of events on one item to trigger event on other widgets. It also shows
+ how you can use the Transfer object to morph data values from one format to
+ another. In this specific case, it maps the values from a dojo.data Datastore
+ item into values stored in a JavaScript Array, which is the format required for
+ the addRow method of the demonstration TableContainer.
+
+ Note that this demo expects dojo, digit, and dojox to all be peers in the same directory
+ in order for it to execute.
