To download CI build artifacts from S3, set up your AWS credentials and run tools/download-s3.py <tag|sha1>, the artifacts will be downloaded into dl-<tag|sha1>.

To upload binary packages to PyPi (test.pypi.org in this example to be safe), do:

$ twine upload -r test dl-<tag|sha1>/*

To build the manylinux Python packages follow these steps:

NOTE: Docker is required.

Install cibuildwheel:

$ pip install -r tools/requirements-manylinux.txt

Build using cibuildwheel:

$ tools/cibuildwheel-build.sh wheelhouse

To skip Python platform configurations, use glob matching in CIBW_SKIP env. This example only builds for Python 2.7 x64:

$ CIBW_SKIP="cp3* cp*i686*" tools/cibuildwheel-build.sh wheelhouse

Packages will now be available in wheelhouse/
