Is it possible to get pip to print the configuration it is using?

Question

Is there any way to get pip to print the config it will attempt to use? For debugging purposes it would be very nice to know that:

You can run pip in pdb. Here's an example inside ipython:

>>> import pip
>>> import pdb
>>> pdb.run("pip.main()", globals())
(Pdb) s
--Call--
> /usr/lib/python3.5/site-packages/pip/__init__.py(197)main()
-> def main(args=None):
(Pdb) b /usr/lib/python3.5/site-packages/pip/baseparser.py:146
Breakpoint 1 at /usr/lib/python3.5/site-packages/pip/baseparser.py:146
(Pdb) c
> /usr/lib/python3.5/site-packages/pip/baseparser.py(146)__init__()
-> if self.files:
(Pdb) p self.files
['/etc/xdg/pip/pip.conf', '/etc/pip.conf', '/home/andre/.pip/pip.conf', '/home/andre/.config/pip/pip.conf']

The only trick here was looking up the path of the baseparser (and knowing that the files are in there). If you don't know this already you can simply step through the program or read the source. This type of exploration should work for most Python programs.
