# A tiny shim around the OCLC's java code that performs NACO normalization,
# used by libraries (and others) to normalize author and title strings for
# sorting purposes.

# See http://www.loc.gov/aba/pcc/naco/normrule-2.html

# Java code adapted from https://code.google.com/p/oclcnaconormalizer/ and copyright OCLC

  # @param [Hash] opts The hash of options
  # @option opts [Boolean] :keep_first_comma (true) Keep the first comma. Defaults, for Lastname,Firstname name data

  # @example
  #  author_normalizer = NacoNormalizer.new
  #  title_normalizer  = NacoNormalizer.new(:keep_first_comma => false)

  #  sortable_author = author_normalizer.normalize(author_name)
