The package installs like most other Python packages.
The most convenient is to use Pypi with pip or easy_install.
pip install ngs_plumbing
#or
easy_install ngs_plumbing
The package can also be dowloaded manually from Pypi and once uncompressed:
python setup.py install
After installing, testing that everything is looking fine is generally a good idea. Unit tests can be run easily with:
python -m ngs_plumbing.tests
The code repository is on bitbucket: https://bitbucket.org/lgautier/ngs_plumbing
Changes across the different versions are reported in the changelog file (see Change logs).
