+"""Connection pooling for DB-API connections.
+
+Provides a number of connection pool implementations for a variety of
+usage scenarios and thread behavior requirements imposed by the
+application, DB-API or database itself.
+
+Also provides a DB-API 2.0 connection proxying mechanism allowing
+regular DB-API connect() methods to be transparently managed by a
+SQLAlchemy connection pool.
