newt

newt is a build and project management tool that hides most of the messy details of creating, building and debugging

mynewt projects. With newt, you don't need to worry about makefiles, compiler flags, debug config settings, and library

versions or updates. The details are elegantly hidden behind the easy to use 'newt' wrapper.

For full details on newt and the entire command set see the official newt documentation (https://adafru.it/Ers).
