| # 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). |
