    Many standard library modules contain code that is invoked on their execution
    as a script.  An example is the :mod:`timeit` module::
 
-       python -mtimeit -s 'setup here' 'benchmarked code here'
-       python -mtimeit -h # for details
+       python -m timeit -s 'setup here' 'benchmarked code here'
+       python -m timeit -h # for details
