A homebrew formula for installing bsdgames-osx (updated for macOS Sierra). For now, just plunk it into /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/bsdgames-osx.rb (or, put it in ~/.homebrew/Library/Formula/ and specify this path when installing) and run "brew install bsdgames-osx". Tested successfully with MacOS X 10.12.3.
