snapy 0.0.7

python extension for SNAP model

This folder contains wrapper functions for the python extension of Athena/HARP.

It uses Cython as the software to extend the existing C++ modules

To install cython, execute:

pip install Cython

More information can be found at http://docs.cython.org/

I found that it is hard to distribute cython project to python

Here's the problems I encountered

1. the extern keywords import header files counting from the 'setup.py' directory

2. the pxd file uses relative import

3. the pyx file uses absolute import

4. pypi needs manylinux tag
