Documentation? Well, there are some comments in the source file... doctest monkey-patches pdb.set_trace (in an ugly way, IMHO) to restore sys.stdout, because you want the output from pdb commands like 'list' or 'print' to go to your console, and not to the doctest's actual result StringIO collector. > Apparently, "doctest" has replaced my "set_trace" in "zpdb" > by its non working implementation of "set_trace". I find it hard to believe. It's more likely that zpdb is interacting with pdb.set_trace in a way that conflicts with doctest's monkey-patch.
