Neopolitan Section: scriptsrc

The `scriptsrc`` section is a metadata section used to load external scripts into the head of the document.

Code
-- scriptsrc
-- url: /some/path.js

Will add this just before the ending `</head>`html` tag.

Code
<script src="/some/path.js"></script>

Other arguments can be added as well. For example, this:

Code
-- scriptsrc
-- url: /some/path.js
-- type: module

Produces this:

Code
<script src="/some/path.js" type="module"></script>
