NavCog3 shows a list of servers at the initial page. Server list will be defined by the following steps

1. if the app has "serverlist.txt" in document directory (you can add the file via iTunes), it access to the url in the file

• file should have only one line url text

2. if the app has "serverlist.json" in document directory, use it as a server list
3. otherwise, access to https://hulop.github.io/serverlist.json

See here for the detail of server list specification.

NavCog3 configures its functions with the selected server config. {<selected_server>} is a json object of the selected server in the server list

1. if {<selected_server>} has config_file_name property then it accesses to https://<hostname>/config/<config_file_name>
2. otherwise access to https://<hostname>/config/server_config.json

See here for the detail of server config specification.
