It is not very clear to me whether SolrCloud is a separate package or a part of Solr package (in 4.x)? I was reading http://wiki.apache.org/solr/SolrCloud. Initially I thought SolrCloud is a separate package but as I read thru the wiki page, I got an impression that SolrCloud is a part of the Solr package?
If someone could clarify, that will be great.
