Python module quick steps

gistfile1.txt

put module code in a git repo, push to github

pip install -e /path/to/module/code
pip install -e git+https://github.com/<project.git>#egg=master <-- installs to $HOME/src/master for further developing 
pip install git+https://github.com/<project.git>#egg=master <-- pip installs from a git repo, rather than pypi

register a username at both http://test.pypi.org and http://pypi.org.

Setup ~/.pypirc file:  
```[distutils]
index-servers =
  pypi
  pypitest

[pypi]
username=<username>
password=<password>

[pypitest]
repository=https://test.pypi.org/legacy/
username=<username>
password=<password>
```
Update version number in setup.py
Run in root directory of module repo:  
  python setup.py sdist upload -r pypitest  
  python setup.py sdist upload -r pypi

Sometime in future:
  python setup.py sdist
  twine upload --repository-url https://test.pypi.org/legacy/ dist/<tarball>
  twine upload dist/<tarball>
