+-- This script saves the sub-delay quantity for each file.
+-- When next time the file is opened, sub-delay is automatically restored.
+-- Using `--sub-delay=<sec>` or `x` and `z` key-bindings both work.
+-- But keep in mind that this script distinguishes different files by reading
+-- their 'path' properties. If you use in command line:
+--     `mpv --sub-delay=0.1 example.mkv`
+-- this delay value won't be applied to the same file you open by
+-- double-clicking it.
