Overview

Used for parsing a document in Markdown format.

This parser is based on the kramdown parser and removes the parser methods for the additional non-Markdown features. However, since some things are handled differently by the kramdown parser methods (like deciding when a list item contains just text), this parser differs from real Markdown parsers in some respects.

Note, though, that the parser basically fails just one of the Markdown test cases (some others also fail but those failures are negligible).
