-0::
Store the files instead of deflating them.
-9::
Highest and slowest compression level. You can specify any
number from 1 to 9 to adjust compression speed and ratio.
-<digit>::
Specify compression level. Larger values allow the command
to spend more time to compress to smaller size. Supported
values are from `-0` (store-only) to `-9` (best ratio).
Default is `-6` if not given.
tar
~~~
-<number>::
Specify compression level. The value will be passed to the
compression command configured in `tar.<format>.command`. See
