Yeoman
Yeoman is a generic scaffolding system allowing the creation of any kind of app.
Yeoman is language agnostic. It can generate projects in any language
Yeoman by itself doesn't make any decisions. Every decision is made by generators which are basically plugins in the Yeoman environment.
...with a yeoman generator
