How do you debug sage code?
My favorite way do debug Python code is to use pdb in GUD emacs-mode.
I split the window into two buffers; in one I interact with pdb, in the other I see the code I'm debugging with the current line highlighted. When I step into a function which is defined in a different file, this window automatically shows the content of the new file.
Is it possible to use pdb and GUD with sage? Or is it possible to achieve this effect in a different way?
