It is now distrubuted as a python package on pypi.python.org. So just run Sage withsage pip install train_trackOr if you do not have enough privileges sage pip install user train_trackAlternatively to bypass the access to internet, you can download the tarball from pypi.python.org/simple/train_track and install sage pip install /path/to/train_track0.1.2.tar.gz See also the README.rst file, or alternatively the github repository: https://github.com/coulbois/sagetraintrack We also plan to include it inside the standard Sage distribution and there is a ticket (#20154) at the Sage development web site. Please volunteer to review that ticket. After installing usage is very easy: sage: from train_track import *
