Yeoman is a scaffolding tool written in JavaScript, supported by a who's-who of web dev legends and backed by hundreds (thousands?) of community-written generators, to bootstrap any kind of project from a simple front-end build to all kinds of framework projects.
Wagtail is a beatiful new CMS, written lovingly in Python/Django by the talented folks at Torchbox. Said folks have recently released an official Django template to get started with a Wagtail site with dependencies, Django settings and deployment ready to go - all packaged nicely into a Vagrant box.
I have recently ported this template to a Yeoman generator and feel that some may question why I would take a beautiful piece of python templating and turn it into JavaScript.
