-/**
- * <p>
- * A main class which may be used to start the provisioning server with an "embedded" Jetty server. Configuration is
- * done via the properties file <i>provserver.properties</i>, which should be in the CLASSPATH. The provisioning server
- * may also be packaged with a web.xml and started as a traditional webapp.
- * </p>
- * <p>
- * Most of the work of the provisioning server is carried out within the eight servlets (configured below) that are used
- * to handle each of the eight types of requests the server may receive. In addition, there are background threads
- * started to perform other tasks:
- * </p>
- * <ul>
- * <li>One background Thread runs the {@link LogfileLoader} in order to process incoming logfiles.
- * This Thread is created as a side effect of the first successful POST to the /internal/logs/ servlet.</li>
- * <li>One background Thread runs the {@link SynchronizerTask} which is used to periodically
- * synchronize the database between active and standby servers.</li>
- * <li>One background Thread runs the {@link Poker} which is used to notify the nodes whenever
- * provisioning data changes.</li>
- * <li>One task is run once a day to run {@link PurgeLogDirTask} which purges older logs from the
- * /opt/app/datartr/logs directory.</li>
- * </ul>
- * <p>
- * The provisioning server is stopped by issuing a GET to the URL http://127.0.0.1/internal/halt using <i>curl</i> or
- * some other such tool.
