				//  - src/vs/base/electron-sandbox

				// When /~ is used in the restrictions, it will be replaced with the correct
				// layers that can be used e.g. 'src/vs/base/electron-sandbox' will be able
				// to import '{common,browser,electron-sanbox}', etc.
				//
				// It is possible to use /~ in the restrictions property even without using it in
				// the target property by adding a layer property.
