 * **-c** or **--chaptered** Output a single file per chapter. The `--chaptered` will only work if it follows the `--aac -e:m4a -e:m4b --flac` options.
 * **--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-author &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..). Has precedence over `--keep-author`.
 * **-l** or **--loglevel &lt;LOGLEVEL&gt;** Set loglevel: 0 = progress only, 1 (default) = more information, output of chapter splitting progress is limitted to a progressbar, 2 = more information, especially on chapter splitting, 3 = debug mode
 * **--dir-naming-scheme &lt;STRING&gt;** or **-D**      Use a custom directory naming scheme, with variables. See [below](#custom-naming-scheme) for more info.
 * **--file-naming-scheme &lt;STRING&gt;** or **-F**    Use a custom file naming scheme, with variables. See [below](#custom-naming-scheme) for more info.
