`link_directory` links all the files inside a single
 directory. It's similar to `path/*` since it does not follow
 nested directories.

     //= link_directory "./fonts"

 Use caution when linking against JS or CSS assets. Include an explicit
 extension or content type in these cases.

     //= link_directory "./scripts" .js
