WebLink Component
=================

The WebLink component manages links between resources. It is particularly
useful to advise clients to preload and prefetch documents through HTTP and
HTTP/2 pushes.

This component implements the [HTML5's
Links](https://www.w3.org/TR/html5/links.html),
[Preload](https://www.w3.org/TR/preload/) and [Resource
Hints](https://www.w3.org/TR/resource-hints/) W3C's specifications. It can also
be used with extensions defined in the [HTML5 link type extensions
wiki](http://microformats.org/wiki/existing-rel-values#HTML5_link_type_extensions).

Getting Started
---------------
