a "call" parameter, which is a reference to a function to call for the
hook.
-An optional "scan" parameter, if set to a true value, makes the hook be

-before begining to render pages. This parameter should be set to true if

-be run twice per page build, so avoid doing it for expensive hooks.

An optional "last" parameter, if set to a true value, makes the hook run
after all other hooks of its type. Useful if the hook depends on some other
hook being run first.
make arbitrary changes. The function is passed named parameters `page` and
`content` and should return the filtered content.

### preprocess
Adding a [[PreProcessorDirective]] is probably the most common use of a
well. Whatever the function returns goes onto the page in place of the
directive.

#### `bestlink($$)`
Given a page and the text of a link on the page, determine which
how it will be accessed in a [[PageSpec]]. The function will be passed
two parameters: The name of the page being matched, and the thing to match
against. It may also be passed additional, named parameters. It should return
-true if the match succeeds, and either false or a IkiWiki::FailReason object
-if the match fails.
