+indexes "Luke" was added as a Lucene module. It can be started from the
+binary distribution by calling the shell scripts in the module folder
+or from the source checkout by using `ant -f lucene/luke/build.xml run`.
+Luke provides a Swing-based user interface and can be used to open
+Lucene or Solr (or Elasticsearch) indexes, inspect documents, check index
+commits and segments, or test (custom) analyzers. It also has maintenance
+functions to check index structures and force merge indexes for archival.
+Luke was originally developed by Andrzej Bialecki, later maintained by
+Dmitry Kan and finally rewritten by Tomoko Uchida to use the ASF licensing
+compatible Swing framework (as shipped with JDKs).
