Related to setuptools being discontinued in Python 3.4.

Fixed in 0.2.1

[tonybaloney]

Issue still exists. Package is installed but output is not created (or is in the wrong place?)

[tonybaloney]

Anyone who has access to Windows, if they can run the tox suite on Python 3.4 it should reproduce the issue

[tonybaloney]

Unable to repro, this was actually another issue. Have added tox for future use
