# NOTE: Docker uses their own versions of several programs, installed as docker-*
# They could be installed separately, and linked with their docker-* names,
#   but docker is very picky about exactly which commit of these it's running.
# As such, I will bundle the docker-specific versions in this package,
#   instead of spreading them over multiple packages.

# The exact commit number for these programs is specified in
#   components/engine/hack/dockerfile/binaries-commits in the docker archive.
