# uses a custom mistune renderer to convert Markdown to BBCode. The custom renderer is defined in the bbcode.py file.
# pass --debug to save the output to readme.1stpass (main.py) and readme.finalpass (html2bbcode)
# for further debugging, you can convert the markdown file to AST using md2ast.py. Remember to load the plugin(s) you want to test.
