[Python-markdown-discuss] MarkdownException?

[David W. <wo...@cs...>]

Is there any reason nothing explicitly raises exceptions?  I've uses  
sys.exit() in load_extension, which in retrospect is probably the  
wrong thing to do (if Markdown is being used as a module)... But it  
also didn't feel right to either return None or create an exception  
class and raise that.
