why there is no pskel?
It's only included in the git repo. Actually `pskel` is declared usign the `script=[]` parameter of `setup.py` installation script, which it fails on many occasions to properly install things.

It would work out of the box in all python environments if it was converted into console entry-point:
http://python-packaging.readthedocs.io/en/latest/command-line-scripts.html#the-console-scripts-entry-point
Setuptools will generate an `.exe` on Windows, and guess correctly the path if python-interpreter on POSIX.

I can provide a pull-request, but it would require some minor changes:
- create new `main()` functions on `/pwiz.py` and `/playhouse/pskel`, 
- rename it as `pskel.py`.

Would that be ok?

I read the doc: <http://docs.peewee-orm.com/en/latest/peewee/database.html#generating-skeleton-code>, I test using pskel to generate the skeleton code, but I found the pskel is not exists in my local
