# This script builds various binary from a checkout of the skopeo
# source code. DO NOT CALL THIS SCRIPT DIRECTLY.
#
# Requirements:
# - The current directory should be a checkout of the skopeo source code
#   (https://github.com/containers/skopeo). Whatever version is checked out
#   will be built.
# - The script is intended to be run inside the container specified
#   in the output of hack/get_fqin.sh
# - The right way to call this script is to invoke "make" from
#   your checkout of the skopeo repository.
#   the Makefile will do a "docker build -t skopeo ." and then
#   "docker run hack/make.sh" in the resulting image.
