This system adds support for Markless syntax in both documents and docstrings. When this system is loaded, Staple will automatically scan for documents with the ending mess to use as primary documents on inferred pages. It also adds the source-compiler :markless that can be used to markup documentation source.
To use Markless for docstrings as well, use a customisation like this on your page type:
(defmethod staple:format-documentation ((docstring string) (page my-page))
(let ((*package* (first (staple:packages page))))
(staple:markup-code-snippets-ignoring-errors
(staple:compile-source docstring :markless))))
