I rencently found the following sort code on the interenet:

CODE
$if(%album%,$if(%various%,Various Artists,$if($strcmp(Various Artists,$directory(%_path%,2)),Various Artists,%artist%))': ''"'%album%[ '(CD'$replace($upper($if2(%disc%,%cd%)),'CD',,'DISC',)')']'"'[ '['$if2(%year%,%date%)']'],%artist%)|$if(%tracknumber%,$num(%tracknumber%,2). ,)$if(%various%,%artist% - %title%,$if($strcmp(Various Artists,$directory(%_path%,2)),%artist% - %title%,%title%))


It works well with %various% tags, however, I don't have a clue what the above code does. Can someone please explain it to me?
