# Usage: dashboard/packaging/werkregie-deploy
#
# The buildCommand of Werkator's build "deploy", which follows a green build of main.
# It builds the runtime bundle of the tested commit and hands it to werkregie-deploy-receive,
# the forced command of the deploy key on the server.
# Where the server is and which key opens it, the host says in the ssh configuration of the build's home,
# as the alias werkregie-deploy, so that the build works natively and in the sandbox alike;
# DEPLOY_TARGET overrides the alias.
# One connection carries the bundle and the answer, since Hostsharing refuses connections that follow too quickly;
# a refused one is tried again (werkrevisor PR#70).
