abcde and uppercase filenames

[Dave]

    Hello,
    Happy New Year.     I'm running abcde 2.3.3 port on FreeBSD 6.x. I'm 
wanting to convert all uppercase paths/filenames in my output from first 
character uppercase or whatever character is uppercase, to all lowercase. I 
first uncommented the mungegenre function in /usr/local/etc/abcde.conf, that 
didn't do it. I then replaced the tr call with "A-Z a-z" This gave me the 
same results, first letter of each word or filename path uppercase. If 
anyone has a fix i'd like to hear about it.
Thanks.
Dave.
