# Version: v0.1.0 | Status: DEVELOPMENT
# ---------------------------------------------------------------------------
# Purpose:  Orchestrator — installs zypper packages from an external,
#           hand-edited package list instead of a one-off script per
#           project. Add new package-list-driven subscripts under lib/ as
#           new package managers are needed (kept fully separate per
#           subscript — never combined, see spec/main_spec.md).
# Target:   SUSE family (zypper). Common orchestrator, distro-specific
#           subscripts.
# Entry:    ./main.sh [package-list-file]
# Depends:  lib/ce-common.sh, lib/00_preflight.sh, lib/10_zypper-packages.sh
# ---------------------------------------------------------------------------
# Orchestrator: exempt from the 100-line subscript boundary (argument
# parsing and subscript dispatch legitimately require it) — see
# ceos_script_architecture.md.

Usage: $(basename "${0}") [package-list-file]

Installs zypper packages listed in package-list-file (default:
local/zypper.list — gitignored, machine-specific; copy
packages/zypper.list.example there to start one) — one package name
per line, '#' comments and blank lines ignored.

Each package manager gets its own dedicated subscript under lib/,
invoked separately; this orchestrator never mixes zypper and pip/pipx
installs in the same run.
