+39. Fixtures.
+
+Fixtures are a way of loading data into the database in bulk. Fixure data 
+can be stored in any serializable format (including JSON and XML). Fixtures 
+are identified by name, and are stored in either a directory named 'fixtures'
+in the application directory, on in one of the directories named in the 
+FIXTURE_DIRS setting.
