A recursive-descent parser for RDoc markup.
The parser tokenizes an input string then parses the tokens into a Document. Documents can be converted into output formats by writing a visitor like RDoc::Markup::ToHTML.
The parser only handles the block-level constructs Paragraph, List, ListItem, Heading, Verbatim, BlankLine and Rule. Inline markup such as +blah+ is handled separately by RDoc::Markup::AttributeManager.
To see what markup the Parser implements read RDoc. To see how to use RDoc markup to format text in your program read RDoc::Markup.
