Anybody have experience with FBSimulatorControl?

Long time lurker, answerer, first time poster.

Wanted to know if anyone out there has tried to use FBSimulatorControl, source found here:

This open source tool bills itself as, “A Mac OS X library for managing, booting and interacting with multiple iOS Simulators simultaneously.” It’s something I’m interested in knowing more about, & will be exploring but I just wanted a little insight into what others have done with this.

Many thanks,
