DESCRIPTION

12       WARNING:

14          in the next release.

16       Pull a Docker image named IMAGE[:TAG] from Docker Hub  and  flatten  it
17       into a Charliecloud tarball in directory OUTDIR.
18
19       This  runs  the following command sequence: docker pull, ch-builder2tar
20       but provides less flexibility than the individual commands.
