* **--continue &lt;CHAPTERNUMBER&gt;** If the splitting into chapters gets interrupted (e.g. by a weak battery on your laptop) you can go on where the process get interrupted. Just delete the last chapter (which was incompletely generated) and redo the task with "--continue &lt;CHAPTERNUMBER&gt;" where CHAPTERNUMBER is the chapter that got interrupted.
