/**
 * Hauptklasse von Calypso
 * 
 * Aufruf mit<br>
 * java -jar calypso.jar port=9000 ctx="/calypso"<br>
 * java -jar calypso.jar nfs-prefix="/media/mc" port=9000<br>
 * java -Djava.util.logging.config.file=logging.properties -jar ..<br>
 * 
 * Der Parameter nfs-prefix bewirkt, dass beim Abspielen relative Pfade 
 * mit diesem Praefix verbunden werden und setzt voraus, dass auf der 
 * Maschine ein NFS-Mount ueber /etc/fstab eingerichtet ist.<br>
 * <br>
 * Anmerkung anlaesslich der Aenderung auf VLC (2.1.2023):<br>
 * Mit Calypso wurde erstmals jdk.httpserver anstelle von Tomcat 
 * einsetzt. Es war in diesem Punkt noch ein Laborversuch und sollte 
 * unter Wiederverwendung der wesentlichen Teile bei Gelegenheit 
 * neu gebaut werden.
