No: jka-compr is only used for compression-only format, like gzip,
compress, bzip, lzma, ... for archives of files (compressed or not),
it's either tar-mode (used for tarballs) or arc-mode (used for ar, zip,
lha, zoo, ...).

   Extracting the individual files in the archive sometimes needs to run
   tan external program.
