+Simple example of a CLI that demonstrates fish-style auto suggestion.
+
+When you type some input, it will match the input against the history. If One
+entry of the history starts with the given input, then it will show the
+remaining part as a suggestion. Pressing the right arrow will insert this
+suggestion.
