Collection of common interactive command line user interfaces, based on Inquirer.js.
Goal and Philosophy
Born as a Inquirer.js clone, it shares part of the goals and philosophy.
So, Inquirer should ease the process of asking end user questions, parsing, validating answers, managing hierarchical prompts and providing error feedback.
