Vendoring in std and cmd
========================

The Go command maintains copies of external packages needed by the
standard library in the src/vendor and src/cmd/vendor directories.

There are two modules, std and cmd, defined in src/go.mod and
src/cmd/go.mod. When a package outside std or cmd is imported
by a package inside std or cmd, the import path is interpreted
as if it had a "vendor/" prefix. For example, within "crypto/tls",

        final CommandExtractor extractor = new CommandExtractor();

        String cmd = "";
        final Map<String, String> params = new HashMap<String, String>();
        List<String> list = extractor.parseCommand(cmd, params);
        assertEquals(0, list.size());

        cmd = "test.sh";
        params.clear();
        list = extractor.parseCommand(cmd, params);
        assertEquals(1, list.size());

	cmd = exec.Command(goTool, "list", "-f", "{{.Target}}", "cmd/go")
	cmd.Stderr = os.Stderr
	out, err = cmd.Output()
	if err != nil {
		return fmt.Errorf("%v: %w", cmd, err)
	}
	platformBin := filepath.Dir(string(bytes.TrimSpace(out)))
	if platformBin == "." {
		return errors.New("failed to locate cmd/go for target platform")
	}
