+## **copy_bundle_data**: Declare a target that copy "bundle_data" files.
+
+```
+  Similar to the "copy" target, but the list of files to copy comes
+  from the "bundle_data" property of all dependencies recursively.
+  It can be used to copy files required at runtime by the application
+  into a location where it can be found.
+
+  This uses the "copy_bundle_data" tool from the toolchain.
+
+  See "gn help copy" for more information.
