ITunes Library Persistent ID Editor.

Sample usage:

fxml = 'iTunes Music Library.xml'    # path to xml file
fitl = 'iTunes Library.itl'          # path to itl file

itk = ITunesLibKeys(fxml, fitl)

print itk.file_xml                   # prints path to xml file
print itk.file_itl                   # prints path to itl file
print itk.xml_key                    # prints key on xml
print itk.itl_key                    # prints key on itl
print itk.valid_key                  # prints True if keys match

itk.new_user_key()                   # ask for user input key

itk.xml_key_replace(itk.itl_key)     # replace key on xml file with the itl key

itk.itl_key_replace(itk.new_key)     # replace key on itl with user input key
