+# virtualenv.

+# This is needed to work around this issue with setuptools:
+# https://bitbucket.org/pypa/setuptools/issue/141
+#
+# In summary: if a different version of one of the "setup_requires"
+# dependencies is globally installed, then setuptools will abort with
+# a VersionConflict exception. Building in a virtualenv works around
+# the bug.
