 * **--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 got 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.
 * **--level &lt;COMPRESSIONLEVEL&gt;**      Set compression level. May be given for mp3, flac and opus.
 * **--keep-artist &lt;FIELD&gt;**           If a book has multiple authors and you don't want all of them in the metadata, with this flag you can specify a specific author (1 is the first, 2 is the second...) to keep while discarding the others.
+* **--author &lt;AUTHOR&gt;**               Manually set the author metadata field, useful if you have multiple books of the same author but the name reported is different (eg. spacing, accents..)
