# Builds the Hugo site and rsyncs ./public/ to saboserver:/srv/www.
# Works from any machine that has the repo + an ssh alias for "saboserver".
#
# Usage:
#   ./deploy_website.sh           # build + deploy
#   ./deploy_website.sh --dry-run # build + show what rsync WOULD transfer
#   ./deploy_website.sh --no-build # skip hugo build, just rsync existing public/
