  module Parser

    # 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).
