#!/usr/bin/env bash
# create-release-manifest.sh — Build a release manifest for the Archipelago update system.
#
# Generates a JSON manifest with version info, changelog, and SHA256 hashes for
# each component, matching the format expected by core/archipelago/src/update.rs.
#
# Usage:
#   ./scripts/create-release-manifest.sh --version 0.2.0 --date 2026-04-01
#
# The script reads built artifacts from the build output directories and produces
# a manifest.json file suitable for hosting at the UPDATE_MANIFEST_URL.
