Config XML

About

Config.xml can be used to configure Itokawa's settings such as listening port. The config will be used by both the main server application and the cli application.

Location

By default, config.xml can be found in ~/.itokawa/config.xml. If the file doesn't exist, default settings will be used. By using the --datadir PATH command line argument, an alternative directory can be used for loading the config and data.

Example File

<config>
    <application>
        <log>
            <level>INFO</level>
        </log>
    </application>

                <subdomain>alex</subdomain>
                <authtoken>12345</authtoken>
