I think what we'll do is have a completely separate download for Python 3. That way, things will just work seamlessly with things like pip and easy_install (or at least I hope so). As I noted on the Python 3 issue, `setup.py build` appears to work correctly in the sympy-py3k directory, so it should be straightforward.

So this should probably be something like, "This is the Python 2 version of SymPy. To use SymPy with Python 3, please obtain a Python 3 version from http://sympy.org, or use the bin/use2to3 script if you are using the git version."
