How to: hiding from google
tell search engines you don't wanna be indexed,  either using the good old [robots.txt](https://www.robotstxt.org/robotstxt.html) or through copyparty settings:

* `--no-robots` adds HTTP (`X-Robots-Tag`) and HTML (`
`) headers with `noindex, nofollow` globally
* volflag `[...]:c,norobots` does the same thing for that single volume
* volflag `[...]:c,robots` ALLOWS search-engine crawling for that volume, even if `--no-robots` is set globally

also, `--force-js` disables the plain HTML folder listing, making things harder to parse for *some* search engines -- note that crawlers which understand javascript (such as google) will not be affected
