I was starting to think about reducing dependencies.  I used 
`src/utilities/finddeps.py` to find dependencies.
Later I will classify those dependencies as you said below 
(install_requires, tests_require and extras_require).
That quote is added as motivation for me :)  Now I have enough 
motivation, so I will remove it :)

I think we can follow this line.

This is a requirement for me also for 2nd March at FOSS.NITC : 
http://www.foss.nitc.ac.in
I will be talking about Zope Component Architecture, I have 2 hour time,
but the audience may not be Python programmers :(
Any advise ?

Why we requires these two:

  tests_require = ['zope.testing'],
  extras_require = dict(

test = ['zope.testing'], ),


Let's use 'tests_require' for test requirements and 'extras_require' for 
other requirements ?

May be I can help, any pointer to start?

As I said above, use 'extras_require' for other requirements and 
'tests_require' only for test requirements?
