-- Shows the file that is currently playing in
-- Windows Explorer and maybe Mac OS Finder.
-- I have no idea whether this works on Mac OS.

-- Put this script into either of these directories:
--     %ProgramFiles%\VideoLAN\VLC\lua\extensions\
--     %ProgramFiles(x86)%\VideoLAN\VLC\lua\extensions\
--     %APPDATA%\VLC\lua\extensions\
--     /Applications/VLC.app/Contents/MacOS/share/lua/extensions/

-- Restart VLC for it to take effect.
-- “Reveal in File Manager” should appear in the “View” menu.
