 This is a Python implementation of John Gruber's [Markdown][]. 
 It is almost completely compliant with the reference implementation,
 though there are a few known issues. See [Features][] for information 
 on what exactly is supported and what is not. Additional features are 
 supported by the [Available Extensions][].
