+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
