python-unity-singlet 0.2.2-0ubuntu1 (arm64 binary) in ubuntu trusty

 Singlet targets opportunistic programmers who want to get search results into
 Unity with the least amount of work. By providing a handful of Python meta
 classes and base classes, Singlet lets you write a basic lens with a minimal
 amount of fuss. It hides all of the boilerplate code necessary to interface
 with GObject and DBus, leaving the developer free to focus solely on the
 purpose of their lens. With Singlet, the only thing a Lens author really
 needs to provide is a single search function.
