# Create manylinux2014 wheels for psycopg2
#
# manylinux2014 is built on CentOS 7, which packages an old version of the
# libssl, (1.0, which has concurrency problems with the Python libssl). So we
# need to build these libraries from source.
#
# Look at the .github/workflows/packages.yml file for hints about how to use it.
