<p>
Kevin Lawson is contributing source code he developed to the Lucene Core project. See
<a href="https://issues.apache.org/jira/browse/LUCENE-4947">LUCENE-4947</a> for more
details.
</p>
<p>
LevenshteinAutomaton is a fast and comprehensive Java library capable of performing
automaton and non-automaton based Levenshtein distance determination and neighbor
calculations. The collection of related utilities affords developers the luxury of
choosing the most appropriate edit distance-related procedure for their needs at any
given time.
</p>
<p>
MDAG (minimalistic directed acyclic graph) is used by the automaton code to store and
step through word sets.
</p>
<p>
The LevenshteinAutomaton and MDAG sources are currently hosted on Github at
<a href="https://github.com/klawson88/LevenshteinAutomaton">https://github.com/klawson88/LevenshteinAutomaton</a>, and
