Add Delicious Library <http://www.delicious-monster.com/> importer and small sample set. This is way more fun than processing MARC records! To launch Solr properly for this dataset, cd solr: java -Dsolr.solr.home=../examples/delicious_library/ -jar start.jar - this will keep this index separate from any others you may be experimenting with.
