     identifier. For example, you can create a Configurable that has a "database" Service in its attribute, meaning that
     you'll define which database to use, by name, when creating the instance of this class, then provide an
     implementation when running the graph using a strategy.

     Example::
-    
+
         import bonobo
-    
+
         class QueryExtractor(bonobo.Configurable):
             database = bonobo.Service(default='sqlalchemy.engine.default')
-            
+
         graph = bonobo.Graph(
             QueryExtractor(database='sqlalchemy.engine.secondary'),
             *more_transformations,
         )
-        
+
         if __name__ == '__main__':
             engine = create_engine('... dsn ...')
             bonobo.run(graph, services={
                 'sqlalchemy.engine.secondary': engine
             })
-

     The main goal is not to tie transformations to actual dependencies, so the same can be run in different contexts
     (stages like preprod, prod, or tenants like client1, client2, or anything you want).
 
     .. attribute:: name
 
         Service name will be used to retrieve the implementation at runtime.
