SpiceyPy is currently supported on Mac and Linux. To install, first simply clone the repository by running the following in your favorite shell:
git clone email@example.com:AndrewAnnex/SpiceyPy.git
If you do not have git, you can also directly download the source code from the GitHub repo for SpiceyPy at https://github.com/AndrewAnnex/SpiceyPy
To install the library, simply change into the root directory of the project and then run:
python setup.py install
The installation script will download the appropriate version of the SPICE toolkit for your system, and will build a shared library from the included static library files. Then the installation script will install SpiceyPy along with the generated shared library into your site-packages directory.
