An example Package.swift showing the correct way to import dependencies.
|// The swift-tools-version declares the minimum version of Swift required to build this package.|
|let package = Package(|
|// Dependencies declare other packages that this package depends on.|
|// .package(url: /* package url */, from: "1.0.0"),|
|.package(url: "https://github.com/kylef/Commander", from: "0.6.0"),|
|// Targets are the basic building blocks of a package. A target can define a module or a test suite.|
|// Targets can depend on other targets in this package, and on products in packages which this package depends on.|
