+"""SQL connections, SQL execution and high-level DB-API interface.
+
+The engine package defines the basic components used to interface
+DB-API modules with higher-level statement construction,
+connection-management, execution and result contexts.  The primary
+"entry point" class into this package is the Engine and its public
+constructor ``create_engine()``.
