+ * (./) udp.pde - how to use UDP library as unicast connection
+ * (cc) 2006, Cousot stephane for The Atelier Hypermedia
+ * (->) http://hypermedia.loeil.org/processing/
+ *
+ * Create a communication between Processing<->Pure Data @ http://puredata.info/
+ * This program also requires to run a small program on Pd to exchange data
+ * (hum!!! for a complete experimentation), you can find the related Pd patch
+ * at http://hypermedia.loeil.org/processing/udp.pd
+ *
+ * -- note that all Pd input/output messages are completed with the characters
+ * ";\n". Don't refer to this notation for a normal use. --
