+--[no-]src::
+	By default, `scalar clone` places the cloned repository within a
+	`<entlistment>/src` directory. Use `--no-src` to place the cloned
+	repository directly in the `<enlistment>` directory.

 --[no-]full-clone::
 	A sparse-checkout is initialized by default. This behavior can be
 	turned off via `--full-clone`.
