title: Camel route to delete old files
body: <p>I have a requirement to delete files which do not get a .done file within 24 hours of the time that they drop.  Is there a way to do this with Camel, Spring Xml, so that I can keep all of this processing in one bundle?  So, I would need to find a file with no matching .done file, and where CamelFileLastModified is 24 hours earlier than the current time.  Finding the file with no matching .done file is my concern</p>
