• twisted.manhole, a debugging service;
• twisted.persisted, a collection of object persistance systems
• twisted.protocols, a collection of helper protocols (such as a line-oriented helper, a length-prefixed helper, a netstrings helper, etc);

• twisted.spread, a network transport, serializer and object broker;
• twisted.trial, a unit-testing framework; and
