Subject [compress] AR docs confusion
Date Wed, 03 Jan 2018 00:10:31 GMT
Someone raised an issue over at jdeb

and I have to say I was a little confused about the docs on the AR support
in compress

Commons Compress 1.0 to 1.2 can only read archives using the GNU/SRV4
> variant, support for the BSD variant has been added in Commons Compress
> 1.3. Commons Compress 1.3 also optionally supports writing archives with
> file names longer than 16 characters using the BSD dialect, writing the
> SVR4/GNU dialect is not supported.

Is this what it means?

  Original: r/w
  GNU/SRV4: r
  BSD: unsupported

  Original: r/w
  GNU/SRV4: r
  BSD: unsupported

  Original: r/w
  GNU/SRV4: r
  BSD: r/w

The jdeb issue was actually not related to AR but TAR.
But that's how I stumbled across the docs.
