-- | Backend for the persistent library using mongoDB.
--   
--   MongoDB backend for the persistent library.
@package persistent-mongoDB
@version 1.3.2


-- | Use persistent-mongodb the same way you would use other persistent
--   libraries and refer to the general persistent documentation. There are
--   some new MongoDB specific filters under the filters section. These
--   help extend your query into a nested document.
--   
--   However, at some point you will find the normal Persistent APIs
--   lacking. and want lower level-level MongoDB access. There are
--   functions available to make working with the raw driver easier: they
--   are under the Entity conversion section. You should still use the same
--   connection pool that you are using for Persistent.
--   
--   MongoDB is a schema-less database. The MongoDB Persistent backend does
--   not help perform migrations. Unlike SQL backends, uniqueness
--   constraints cannot be created for you. You must place a unique index
--   on unique fields.
