+-- This script automatically loads playlist entries before and after the
+-- the currently played file. It does so by scanning the directory a file is
+-- located in when starting playback. It sorts the directory entries
+-- alphabetically, and adds entries before and after the current file to
+-- the internal playlist. (It stops if it would add an already existing
+-- playlist entry at the same position - this makes it "stable".)
+-- Add at most 5000 * 2 files when starting a file (before + after).
+
+--[[
+To configure this script use file autoload.conf in directory script-opts (the "script-opts"
+directory must be in the mpv configuration directory, typically ~/.config/mpv/).
+
+Example configuration would be:
+
+disabled=no
+images=no
+videos=yes
+audio=yes
+ignore_hidden=yes
