+SUMMARY="An event-driven networking engine written in Python"
+DESCRIPTION="
+Twisted is an event-based framework for internet applications. It includes \
+modules for many different purposes, including the following:
+
+- twisted.application
+  A "Service" system that allows you to organize your application in \
+  hierarchies with well-defined startup and dependency semantics,
+
+- twisted.cred
+  A general credentials and authentication system that facilitates \
+  pluggable authentication backends,
+
+- twisted.enterprise
+  Asynchronous database access, compatible with any Python DBAPI2.0 \
+  modules,
+
+- twisted.internet
+  Low-level asynchronous networking APIs that allow you to define \
+  your own protocols that run over certain transports,
+
+- twisted.manhole
+  A tool for remote debugging of your services which gives you a \
+  Python interactive interpreter,
+
+- twisted.protocols
+  Basic protocol implementations and helpers for your own protocol \
+  implementations,
+
+- twisted.python
+  A large set of utilities for Python tricks, reflection, text \
+  processing, and anything else,
+
+- twisted.spread
+  A secure, fast remote object system,
+
+- twisted.trial
+  A unit testing framework that integrates well with Twisted-based code.
