+#				Default is "NO".
+# shadowsocks_config (path):	Set the path to the config file
+#				Default is "/usr/local/etc/shadowsocks-libev/config.json",
+#				or "/usr/local/etc/shadowsocks-libev/${profile}.json".

+# shadowsocks_profiles (str):	Set the list of shadowsocks profiles
+#				Default is "".
+#
+# For each profile you can then define different options (except for
