The "healpy" python package (wrapping c code) that is used in astronomy, and currently does not support Windows. This project is to make it support Windows and update the conda package to install the binary build via conda-forge. You can see some discussion about this and suggestions for how to do it here:

Note that the package installation does some slightly non-standard scripting things, so it may take a bit of work. The objective is to update the conda-forge package so that people can simply install it on Windows using "conda install -c conda-forge healpy" as they can now on other platforms.
Your changes should be well tested, pass all the unit tests, and be directly mergeable into the latest it and conda smithy trunk and become live on conda. In your bid please mention your experience with conda-forge, windows and python.
