Re: [bug-libextractor] Handling MP3 files: duplicate types

[Christian Grothoff]

Use the  "-d" option to kill duplicates.  Note that this will not kill two 
entries of the same type if they have different values, so you could still 
get something like

title - New Kid In Town
title - new kid in town

(only case-sensitive, exact matches, similar to what "|sort | uniq" would give 
you are filtered out with -d).

I hope this helps.
