Note that the **only** reliable way to configure MathJax is to use an
in-line configuration of the type discussed above. You should **not**
call :meth:`MathJax.Hub.Config()` directly in your code, as it will
not run at the correct time --- it will either run too soon, in which

configuration process, so your changes will not have the desired
