(from gem rdoc-7.2.0)
------------------------------------------------------------------------
Handle common directives that can occur in a block of text:

  :include: filename

Directives can be escaped by preceding them with a backslash.

RDoc plugin authors can register additional directives to be handled by
using [RDoc::Markup::PreProcess::register](https://www.chedong.com/phpMan.php/perldoc/RDoc%3A%3AMarkup%3A%3APreProcess%3A%3Aregister/markdown).

## Any directive that is not built-in to RDoc (including those registered
via plugins) will be stored in the metadata hash on the CodeObject the
comment is attached to.  See [RDoc::Markup](https://www.chedong.com/phpMan.php/perldoc/RDoc%3A%3AMarkup/markdown)@Directives for the list of
built-in directives.
