+Compiling the source requires the babel (version 6) CLI to be
+available as "babeljs" along with the "react" preset and support for
+"object spread" syntax. This can be achieved on Debian with:
+
+ sudo apt install \
+ node-babel-cli \
+ node-babel-preset-react \
+ node-babel-plugin-transform-object-rest-spread
