The Config Browser is a simple tool to help view your Struts configuration at run-time. It is very useful when debugging problems that could be related to configuration issues.

Installing the Config Browser is a two-step process.

1. Ensure that the FreeMarker JAR is on the classpath.
2. Include the `config-browser.xml` in your `struts.xml` file
   - `<include file="config-browser.xml"/>`

Once configured, you can access the Config Browser by opening to the action named index in the config-browser namespace.

In most cases (if you are using the default ActionMapper), the URL is something like http://localhost:8080/starter/config-browser/index.action.
