 # Path handling for libraries and templates
 # Paths have to be normalized because Jinja uses the exact template path to
 # determine the hash used in the cache filename, and we need a pre-caching step
 # to be concurrency-safe. Use absolute path because __file__ is absolute if
 # module is imported, and relative if executed directly.
 # If paths differ between pre-caching and individual file compilation, the cache
 # is regenerated, which causes a race condition and breaks concurrent build,
