Ok, I am not sure I want to use Request Tracker and RTFM, which is a possible solution.
I'd like to have a knowledge base with my bug tracker/todo list , so that when I solve a problem, I would have a record of its resolution for myself or others later.
What python based solutions are available?
A highly flexible issue tracker in Python I would recommend is "Roundup": http://roundup.sourceforge.net/.
An example of its use can be seen online at http://bugs.python.org/.
