There are two issues with relying on 'setup.py --<field>' to find the 
value of <field>:

1) setuptools prints warning messages to stdout: 
http://bugs.python.org/setuptools/issue73 (does `safe_name()` handle this?)

2) Some packages in PyPI prints unexpected messages depending upon the 
environment (even if you pass --name to setup.py). How do you suggest to 
find name/version under such cases?
