 Please run the tests on both Python2 and Python3 for your pull-reqs!
 
+Alternately, if Tox (see https://tox.readthedocs.org/) is available on your
+system, you can run unit tests for multiple Python versions:
+
+    ./runtests.sh
+
+Currently, the following implementations are tried (any not installed are
+skipped):
+
+    * CPython 2.7
+    * CPython 3.3
+    * CPython 3.4
+    * CPython 3.5
+    * PyPy
+    * PyPy3
+
+HTML coverage reports can then be found in the htmlcov/ subdirectory.
