We use <code>#lang racket/base</code> to show which module system is in. It would be imported anyway if we use the larger <code>#lang racket</code>.

See [http://docs.racket-lang.org/reference/subprocess.html?q=system#%28def._%28%28lib._racket%2Fsystem..rkt%29._system%29%29 documentation for <code>system</code> and friends].
