/**
 * The <a href="http://camel.apache.org/glogin.html">GLogin Component</a>
 * encapsulates the required steps needed to login to an Google App Engine (GAE)
 * application. This component uses <a
 * href="http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html"
 * >ClientLogin</a> for authentication and a GAE-specific mechanism for
 * authorization. Result of the login procedure is an authorization cookie that
 * should be included in HTTP requests targeted at GAE applications. This
 * component is intended for being used by Java client applications that want to
 * do a programmatic login to GAE applications. Web applications should use the
 * {@link GAuthComponent} for access authorization to other web applications.
