/** <module> Phonetic string matching
The library library(double_metaphone) implements the Double Metaphone
algorithm developed by Lawrence Philips and described in "The
Double-Metaphone Search Algorithm" by L Philips, C/C++ User's Journal,
2000. Double Metaphone creates a key from a word that represents its
phonetic properties. Two words with the same Double Metaphone are
supposed to sound similar. The Double Metaphone algorithm is an improved
version of the Soundex algorithm.
@license The Double Metaphone algorithm is copied from the Perl library
that holds the following copyright notice. To the best of our knowledge
the Perl license is compatible to the SWI-Prolog license schema and
therefore including this module poses no additional license conditions.
