I think most anyone reviewing the solr artifacts will do this,
so really the RM has to do it manually:
but we can test 'ant example' from the source dist + java -jar start.jar from solr/example
(or/and 'ant run-example'), and also java -jar start.jar from the binary distribution.
some basic checks we can do are to run the test_utf8.sh, and to index the example docs
(post.jar/post.sh the docs in exampledocs) then do a search.
