How to render gud (python debugger) output?

[Z]

Hi members,

I use gud pdb to debug Python program. But output of gud is mono color
and hard to identify the information in a huge chuck of
output(e.g. type "bt" and find current frame in stack). So I want to add color 
and link to the output.

How to render gud output? What function shall I add or change?

Thank you very much,
Z
