macOS Usage

While the main project only supports Linux, @BKrajancic has contributed this script which allows for exporting the base SVG icons into a .icn format which can be used to replace folder or application icons on macOS. It requires Cairo to be installed for Python 3 and libicns to be installed system wide for the png2icns command.
