[AstroPy] ratholes

[Mark Sienkiewicz]

I note that the discussion of packaging has completely displaced any 
discussion of what astropy is, what it does, or what might be included.

I also note that the packaging mechanism does not matter if we have no 
software to package.  Let me offer this:

- astropy can be installed with "python setup.py install".

- astropy can be installed with "pip install astropy".

- Anything that can be installed via those methods can also be 
distributed via _any_ of the other packaging mechanisms under 
discussion, subject to someone committing to routinely perform the 
packaging work at each release.

I suggest that we declare these three statements as "good enough for 
now" and get back to answering the question "What is astropy?"
