`redirects`: OPTIONAL. A map of URLs where the key will be mapped to the value by Paprika using 301 redirects. This is mainly useful for migration from another blogging platform.

`cache_maxage`: OPTIONAL. A value in seconds determining how long the browser should cache static resources from the blog. If omitted, the default value is a week.

`hljs`: An array of language support from `highlight.js` to be included in the final binary. The full `highlight.js` is notoriously huge and there's really no reason to include a bazillion languages you will never actually use in your blog posts. This will be read by `build.rs` to generate a JS shim that will load all languages in the array to the final binary via `webpack` support for `require`.
