+/**
+ * This file manages a MigrationWizard embedded in a dialog that runs
+ * in a top-level dialog window. It's main responsibility is to listen
+ * for dialog-specific events from the embedded MigrationWizard and to
+ * respond appropriately to them.
+ *
+ * A single object argument is expected to be passed when opening
+ * this dialog.
+ *
+ * @param {object} window.arguments.0
+ * @param {Function} window.arguments.0.onResize
+ *   A callback to resize the container of this document when the
+ *   MigrationWizard resizes.
+ * @param {object} window.arguments.0.options
+ *   A series of options for configuring the dialog. See
+ *   MigrationUtils.showMigrationWizard for a description of this
+ *   object.
