The development of the python package Polygon was moved to github. I created two projects for the code for python 2 and 3.
The project pages at origo.ethz.ch will be closed soon. The information was updated at pypi.python.org, but no code was changed yet. Since there are no known bugs and feature requests right now, new versions are not scheduled for the near future.
