%description
Shifter enables container images for HPC. In a nutshell, Shifter
allows an HPC system to efficiently and safely permit end-users to run
jobs inside a Docker image. Shifter consists of a few moving parts:
  1) a utility that typically runs on the compute node that creates the
     runtime environment for the application,
  2) an image gateway service that pulls images from a registry and
     repacks them in a format suitable for the HPC system (typically
     squashfs), and
  3) example scripts/plugins to integrate Shifter with various batch
     scheduler systems.

This package contains no files; to install the core components of
Shifter, please install the "shifter-runtime" package.

This package contains a utility needed to import images directly
into Shifter.  This is not required to pull docker images and is
optional.  In a remote configuration, this RPM should be installed on
the remote system.
