Original library (published under MIT license): http://code.google.com/p/geodesic/
We added a python wrapped and made small fixes to the original library, to make it compatible with cython.
To install this, either run pip install gdist or download these
sources and run python setup.py install in current folder.
Basic test could be:
python
import gdist
Python 2.7, Cython, and a C++ compiler are required.
In order to produce a Debian package, assuming you have the requisite tools
installed (apt-get install devscripts python-all-dev python-stdeb)
cd debian
debuild -us -uc
cd ../../
and you should find a suitable deb file for your system.
