# Sync the deployable surface to a remote host for `make install`. Pins the
# include list to the seven items the project ships: Makefile, party, party.1,
# README.md, tools/post-install.sh, and tests/ (so the host can run `make
# check` as a target-OS smoke test). This is the dev-rsync variant. The
# release-tarball variant strips tests/ as well; not implemented here.
#
# Usage:
#   ./deploy.sh <host>[:path] [extra rsync args]
#
# Path defaults to `tmux-party-src` (relative to the remote login user's
# home directory) when omitted.
#
# Examples:
#   ./deploy.sh user@domain.tld                         # → :tmux-party-src
#   ./deploy.sh user@domain.tld:dev/tmux-party-src      # explicit path
#   ./deploy.sh user@domain.tld -n                      # dry-run, default path
