is that needed? we already have set -e

    bazel build //:scion-topo || return 1

why the tab here?

	    $PROGRAM version
	        Show version information.
        $PROGRAM traces [folder]

unrelated but, can you please fix the indentation here as well?

I think the change would be less "breaking" if we just left the build command. Just reduce it to make -s

if we remove it we should also remove it in go/lib/integration/README.md
