# sb-publish: push the local package repository to the public mirror.
#
# Usage: sb-publish [PKGREPO]      (default /repo)
#
# Called by rsync_push_hook in slackrepo_SBo-danix.conf after a build, unless
# the build ran with SBB_PUBLISH=n; run it by hand (or from sb-builder's
# Publish action) to push such builds later. Settings come from the root-only
# SB_LOCAL file (default /etc/slackrepo/SBo-danix.local):
#   SB_RSYNC_TARGET          rsync destination (required)
#   SB_RSYNC_PASSWORD_FILE   --password-file, if the file exists
#   SB_RSYNC_EXCLUDES        --exclude-from, if the file exists
