What is Mac OS/iOS CBL Xcode project?

Documentation of Manager states (about 40% down the page):

On iOS / Mac OS, the Couchbase Lite Xcode project has a target called LiteServ that builds a small Mac app that does nothing but run the REST API. LiteServ is a useful tool for creating databases and running replications locally on your development machine.

What/where is this?

I guess it is something located here https://github.com/couchbase/couchbase-lite-ios/tree/master/LiteServ%20App
