webtamp is bundler for assets. It is inspired by webpack, and meant to be a companion to JS-driven bundlers like webpack. You can do a lot of cool and useful things with webpack and its plugin community. However, there are a number of things that either can't be done at all, or can be done poorly and with difficulty by plugin that hack webpack in a way it wasn't meant for. The webpack authors are very clear about the scope and boundaries of webpack and fair enough.
