/**
 * Scheduled job for time based publishing.<p>
 *
 * This class is called via the scheduled job backoffice to publish a project at a given time.<p>
 * 
 * Per default, it publishes all new, edited and deleted resources in the project which are not locked.
 * To unlock all resources in the project before publishing, add the parameter <code>unlock=true</code>
 * in the scheduled job configuration. In addition you are able to perform a link validation before
 * publishing the project by adding the parameter <code>linkcheck=true</code>. It is possible to send
 * an email to a user in OpenCms in case somthing went wrong during this process. To do so specifiy
 * a parameter<code>mail-to-user=username_in_opencms</code>.<p>
