Usage: ./scripts/configure-nextcloud-defaults.sh [options]

Options:
  --compose-file <path>       Compose file to use (default: docker-compose.devprod.yml)
  --env-file <path>           Env file to use (default: .env.devprod)
  --restore-core-skeleton     Restore signed core skeleton files from the configured Nextcloud image
  --purge-existing-user-skeleton
                              Remove known Nextcloud skeleton files from existing user file trees
  --check-integrity           Run occ integrity:check-core after configuration
  --empty-skeleton-dir <path> NuQloud skeleton directory path (default: /var/www/html/data/nuqloud-empty-skeleton)
                              If /var/www/html/nuqloud-skeleton is missing, an empty skeleton is used.
