From the announcement:
NumFOCUS is pleased to announce the newest addition to our fiscally sponsored projects: conda-forge.
Conda-forge builds and distributes software packages, specializing in the hard-to-build or unique packages that often arise in a scientific computing context. Conda-forge is community-driven and community-curated. This means that no package is too domain-specific and all packages undergo review to ensure quality and interoperability.
The conda-forge GitHub organization contains repositories of conda recipes. Thanks to some awesome continuous integration providers (AppVeyor, CircleCI and TravisCI), each repository, also known as a feedstock, automatically builds its own recipe in a clean and repeatable way on Windows, Linux and OSX.
Conda-forge packages include shapely, fiona, and rasterio.
Congratulations, Filipe and Phil!
