unshadow stdlib token from roundup's token. This bites me every now and again when running pytest and pdb. Some submodules want to load the stdlib python and end up getting roundup's python and thing break with N_TOKENS not defined etc. So rename token.py to token_r.py (token_r(oundup)... hey naming things is hard) an change code as needed.

#!/usr/bin/env python

# Roundup requires Python 2.7+ as mentioned in doc\installation.txt
from __future__ import print_function
import sys

if sys.version_info < VERSION_NEEDED:
    print("Content-Type: text/plain\n")
    print("Roundup requires Python %s.%s or newer." % VERSION_NEEDED)
    sys.exit(0)
