often the name of a go subcommand (list, build, test, ...) or concept (vendor, pattern).

Each script is a text archive (go doc internal/txtar).
The script begins with an actual command script to run
followed by the content of zero or more supporting files to
create in the script's temporary file system before it starts executing.

As an example, run_hello.txt says:

	# hello world
	go run hello.go
	stderr 'hello world'
	! stdout .

	// (the one with the fewest dependencies) and its edges from the graph,
	// repeatedly, until there are no nodes left.
	// In a valid Go program, those nodes always have zero dependencies (after
	// removing all incoming dependencies), otherwise there are initialization
	// cycles.
	emitted := make(map[*declInfo]bool)
	for len(pq) > 0 {
		// get the next node
		n := heap.Pop(&pq).(*graphNode)
