Due to the chaotic nature of dynamic adaptation, compressed result is not reproducible.
_note_ : at the time of this writing, `--adapt` can remain stuck at low speed
when combined with multiple worker threads (>=2).
+* `--stream-size=#` :

* `--rsyncable` :
`zstd` will periodically synchronize the compression state to make the
compressed file more rsync-friendly. There is a negligible impact to
This feature does not work with `--single-thread`. You probably don't want
to use it with long range mode, since it will decrease the effectiveness of
the synchronization points, but your milage may vary.

* `-D file`:
use `file` as Dictionary to compress or decompress FILE(s)
* `--no-dictID`:
