					// A path ending in /~ has a special meaning. It indicates a template position

					// When /~ is used in the target, the rule will be expanded to 14 distinct rules.
					// e.g. "src/vs/base/~" will be expanded to:
					//  - src/vs/base/common
					//  - src/vs/base/worker
					//  - src/vs/base/browser
					//  - src/vs/base/electron-sandbox

					//  - src/vs/base/test/node
					//  - src/vs/base/test/electron-browser
					//  - src/vs/base/test/electron-main
					//
					// 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.
