Simple CLI demo

This demonstrates how dynamic values are being updated in a simple CLI app.

Quick set up:

Download etcd, extract and make it available on your $PATH.

Launch etcd server serving from a default.data in /tmp:

cd /tmp
etcd 

Set up a set of flags:

etcdctl mkdir /example/flagz
etcdctl set /example/flagz/example_my_static_int 9090
etcdctl set /example/flagz/example_my_dynamic_int foo

Play around:

./simple_cli &
etcdctl set /example/flagz/example_my_dynamic_string bar
etcdctl set /example/flagz/example_my_dynamic_int 7777
etcdctl set /example/flagz/example_my_dynamic_string bad_value

Profit.
