# This is to be run by Docker inside a Docker image.
# You can test it locally on a Linux machine by installing Docker and running from this
# repo's root:
# $ docker run -v `pwd`:/io quay.io/pypa/manylinux1_x86_64 /io/scripts/build-manylinux-wheels.sh

# The -v gives a directory alias for passing files in and out of the Docker.
# (/io is arbitrary). E.g the setup.py script can be accessed in the Docker via
# /io/setup.py quay.io/pypa/manylinux1_x86_64 is the full Docker image name. Docker
# downloads it automatically.

# The last argument is a shell command that the Docker will execute. Filenames must be
# from the Docker's perspective.

# Wheels are initially generated as you would usually, but put in a temp directory temp-wheels.
# The pip-cache is optional but can speed up local builds having a real permanent pip-cache dir.
