+# This flag says to generate wheels that support both Python 2 and Python
+# 3. If your code will not run unchanged on both Python 2 and 3, you will
+# need to generate separate wheels for each Python version that you
+# support. Removing this line (or setting universal to 0) will prevent
+# bdist_wheel from trying to make a universal wheel. For more see:
