The document summarizes the new Titanium command line interface (CLI). It describes how the previous Python-based CLI was inconsistent, poorly documented, and difficult to use and maintain. The new CLI is built with Node.js and provides a simpler and more consistent experience for creating and building Titanium projects and apps. It allows users to configure SDKs and plugins, get system information, manage modules, authenticate with Appcelerator accounts, and includes new commands for creating projects and building apps.
