> *Name origin*: Astronomer [Annie Jump Cannon](https://en.wikipedia.org/wiki/Annie_Jump_Cannon).
> A cool surname from a celebrity in astronomy, since Cannon works best when
> combined with other BA-ST architecture projects, like [Stardust](https://github.com/ba-st/Stardust)
> and [Kepler](https://github.com/ba-st/Kepler).

With Cannon, we aim to provide a much-needed state machine implementation, which
is required for any complex workflow architecture.
