[ANN]: circuits-1.0a2 released!

Hi all,

I'm pleased to announce the release of circuits-1.0a2

Overview
======

circuits is an event-driven framework with a focus on Component
Software Architectures where System Functionality is defined in
Components. Components communicate with one another by propagating
events throughout the system. Each Component can react to events and
expose events to other parts of the system Components are able to
manage their own events and can also be linked to other Components.

circuits has a clean architecture and has no external dependencies on
any other library. It's simplistic design is unmatchable but yet
delivers a powerful framework for building large, scalable,
maintainable applications and systems. circuits was a core integral
part of the pymills library developed in 2006 and was partly inspired
by the Trac architecture.
