Linux and other Unix systems most of the time come with a very good package managment system supported by puppet. Because of that we don't need a library like boxen to install .dmgs.
Our goal is to provide puppet modules to install laptops or desktop computers using puppet. If you have a Mac you should have a look at boxen
We don't have an interface or something right now, actually you don't need one. Right now there are just 2 small modules which can help to reduce problems.
