// existing Ninja build:
//
// ln -s <project-root>/build/<Ninja-Build>/llvm-<os+arch> <project-root>/build/Default/llvm
// ln -s <project-root>/build/<Ninja-Build>/swift-<os+arch> <project-root>/build/Default/swift
//
// where <project-root> is the parent directory of the swift repository.
//
// FIXME: We may want to consider generating Package.swift as a part of the
// build.
