Source code for myproject4.skeleton

#!/usr/bin/env python
# -*- coding: utf-8 -*-
This is a skeleton file that can serve as a starting point for a Python
console script. To run this script uncomment the following line in the
entry_points section in

    fibonacci = myproject4.skeleton:run

Then run `python install` which will install the command `fibonacci`
inside your current environment.
Besides console scripts, the header (i.e. until _logger...) of this file can
also be used as template for Python modules.

Note: This skeleton file can be safely removed if not needed!
