 This package can be used to pre-compile Vue 2.0 templates into render functions to avoid runtime-compilation overhead and CSP restrictions. You will only need it if you are writing build tools with very specific needs. In most cases you should be using [vue-loader](https://github.com/vuejs/vue-loader) or [vueify](https://github.com/vuejs/vueify) instead, both of which use this package internally.
