+Subject: [PATCH] setup.py: fix python_requires
+
+Fix python_requires to specify a valid version.  Apparently, combining
+>= and .* is disallowed, and I'm pretty sure 'just' >=3.5 means
+the same.
+
+To reproduce the problem, you can:
+
+    $ pip install nltk distlib
+    $ python -c "import distlib.database; \
+      distlib.database.DistributionPath().get_distribution('nltk')"
+
+which yields a (not very readable) error of:
+
+    ValueError: '.*' not allowed for '>=' constraints
