`xPrefix`

If given, prepend the given string to every single internal cross file reference output.

E.g. suppose that you previously had at myoldsite.com you had:

animal.bigb

= Animal

<Dogs> don't eat <bananas>.

== Dog

plant.bigb

= Plant

== Banana

Originally that would render as:

<a href="#dog">Dogs</a> don't eat <a href="plant#banana">bananas</a>.

But then if you set in ourbigbook.json:

{
  "xPrefix": "https://mynewsite.com/"
}

it will instead render as:

<a href="#dog">Dogs</a> don't eat <a href="https://mynewsite.com/plant#banana">bananas</a>.

where:

Scopes are automatically resolved so that they will also be present in the target. E.g. in:

subdir/notindex.bigb

<notindex2>

subdir/notindex2.bigb

= Notindex2

we get on subdir/notindex.html:

<a href="https://mynewsite.com/subdir/notindex2.html">

and not:

<a href="https://mynewsite.com/notindex2.html">
