+-- The known maintainer for each package is stored in a plain text cache file

+-- package the current maintainer is recorded without any warning. On
+-- subsequent upgrades:

+--   * different maintainer → error "new maintainer, double check build files"
+--
+-- The cache is updated whenever a new or changed maintainer is seen.
+--
+-- Cache file location: <cache_dir>/maintainer_cache
+-- Format: one "pkgname=maintainer" entry per line.

+-- missing reliable cfg getter
