Note: It is only necessary to use the first two (or more) characters of any
subcommand, enough that the abbreviation is unique. Such as: ``demonstrate``
can be abbreviated to ``demo`` or even ``de``.

This was not caught by the unit testing.

[prjemian]

Happens with the installed version on Linux, too. But does not happen when running from the source code.

[prjemian]

It works correctly when installed from the source directory:

Suspect something in the packaging.

[prjemian]

locally built distributions work just fine

pushd dist/
pip install -U --no-deps punx-0.1.7+2.g538d9b9.tar.gz
punx demo
pip install -U --no-deps punx-0.1.7+2.g538d9b9-py2.py3-none-any.whl
punx demo

[prjemian]

next, download and check the two distributions from https://pypi.python.org/pypi/punx/

[prjemian]

one item missing: __github_info__.json from each definitions cache

[prjemian]

source cache in packaged distribution is not being found (discovered this by adding debug statements)

[prjemian]

That's it, the .json file in the source cache was not packaged
