Marked-Up Text Viewer for Python/Tkinter

[James Stroud]

Hello All,

I'm wondering if there is something that already exists that can take 
marked up text in some format (hopefully reStructuredText or HTML) and 
can convert it into something that can be displayed with Tkinter (maybe 
with Text), either dynamically or otherwise. Minimal functionality would 
be simple formatting and hyperlink callbacks.

Any guidance or suggestions would be appreciated.

Thank you in advance for your help.

James
