%description
Parses real-world 'HTML' with a bundled copy of the 'Gumbo' parser
(<https://codeberg.org/gumbo-parser/gumbo-parser>), which follows the
'WHATWG' parsing algorithm, so that no system library is required.
Documents become immutable trees navigated with a documented subset of
'CSS' selectors. Attributes, text, lists, tables, links, forms and page
metadata ('JSON-LD', microdata) are extracted into ordinary character
vectors, lists and data frames, and nodes convert to 'Markdown'. Input is
a string, raw bytes, a file, a URL or a connection, and raw input is
decoded as browsers decode it, from a byte-order mark or a '<meta>'
declaration. Parsing is bounded by limits on input size, native memory and
nesting depth.
