generator-magentomodule 
A Yeoman generator for Magento modules.
Getting Started
Not every new computer comes with a Yeoman pre-installed. He lives in the npm package repository. You only have to ask for him once, then he packs up and moves into your hard drive. Make sure you clean up, he likes new and shiny things.
$ npm install -g yo
Yeoman Generators
Yeoman travels light. He didn't pack any generators when he moved in. You can think of a generator like a plug-in. You get to choose what type of application you wish to create, such as a Backbone application or even a Chrome extension.
To install generator-magentomodule from npm, run:
$ npm install -g generator-magentomodule
Finally, initiate the generator:
$ yo magentomodule
Then simply answer the questions and thats it.
