Note: Builder requires Swift 4.2
This is an example project for Builder, which is a build tool layered on top of the Swift Package Manager.
To build this example:
swift run builder run
What this command does is to ask the Swift Package Manager to build and run the product called builder, and to pass it the argument run.
The builder product is supplied by the Builder project, which is listed as a dependency in Package.swift.
When builder runs, it builds and runs the Configure target, which gives it a configuration.
It then looks up the run action in the configuration. This tells Builder what to do to build and run the example product.
The nice thing about all of this is that the build relies on three external dependencies (Builder itself, BuilderConfiguration, and an example tool BuilderToolExample), but you don't have to do any preliminary fetching or installing of things. As long as you have swift installed, you're good to go.
