./release.sh 0.42.3

Build the PyPI package in the dist folder

make build

Deploy the package to PyPI test repository (prefix the command with a space for the shell to not save it in its history system, since the command contains credentials)

[SPACE]make deploy_test PYPI_TEST_LOGIN=xxxx PYPI_TEST_PASSWORD=xxxx

Install the package from PyPI test repository

pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.python.org/simple/ duniterpy
