The Enso Project is the open-source release of Enso, an extensible, cross-platform quasimodal linguistic command-line interface written in Python.

Enso's goal is to provide a way of accessing whatever piece of functionality you need -- be it calculating an expression, calling up a map, or performing a Google search -- with a few, semantically meaningful keystrokes.
