# NOTE: This workflow was ported from Travis.
# Travis was using Ubuntu 14.04. Ubuntu 14.04 is not supportted by GitHub workflows. Ubuntu 20.04 is recommended.
# Travis was using Clang 3.6. The earliest version support by Ubuntu 20.04 is Clang 6.0.
# Travis was caching the clang package. APT package caching is not natively supported by GitHub actions/cache.
# Travis was using Mac OS X 10.13.6 / Xcode 9.4.1 / LLVM 9.1.0
