+ * devpath resources.
+ *
+ * Most resources in config files will be in one of the following formats:
+ *  - URLs
+ *  - device-local filenames (ie, filenames on the currently-discovered dev)
+ *  - other-device filenames (which speficy the device by a string format,
+ *     using a dev:path format).
+ *
+ * The following definitions are a generic resource handler for these types
+ * of resources. By creating resources with create_devpath_resource,
+ * parsers can use resolve_devpath_resource as their resolve_resouce
+ * callback.
