-- 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 the it would add an already existing
|
|
-- playlist entry at the same position - this makes it "stable".)
