+# Levenshtein distance algorithm implementation for Ruby, with UTF-8 support
+#
+# Author::  Paul BATTLEY (pbattley @ gmail.com)
+# Version:: 1.3
+# Date::    2005-04-19
+#
+# == About
+#
+# The Levenshtein distance is a measure of how similar two strings s and t are,
+# calculated as the number of deletions/insertions/substitutions needed to
+# transform s into t.  The greater the distance, the more the strings differ.
+#
+# The Levenshtein distance is also sometimes referred to as the
+# easier-to-pronounce-and-spell 'edit distance'.
+#
+# == Revision history
+#
+# * 2005-05-19 1.3 Repairing an oversight, distance can now be called via
+#   Levenshtein.distance(s, t)
+# * 2005-05-04 1.2 Now uses just one 1-dimensional array.  I think this is as
+#   far as optimisation can go.
+# * 2005-05-04 1.1 Now storing only the current and previous rows of the matrix
+#   instead of the whole lot.
