+ * 28.11.2014, Adrian Scarlat, Added code to allow only one instance of
+ *                             AM PoC to run; This was achieved by creating
+ *                             a file in /var/run and placing an advisory
+ *                             lock on it, using flock(). When another
+ *                             instance is created, it can't create the advisory
+ *                             lock on the same file since the first instance
+ *                             owns it and it will quit with an appropriate
+ *                             message.
