+Basic applications for panStamp.
+
+1. simpletest : basic "blink a LED" application.
+
+2. basicbeacon : Basic wireless beacon transmitter.
+
+3. basicradio : Basic bi-directional application that pairs with another
+   basicradio node and toggles an LED whenever a packet is received.
+
+4. modem : Serial wireless modem that interfaces between a network of panStamps
+   and a serial port (RS232, USB, ...). This application is used as the modem for
+   all computer applications developed for panStamp.
+
+   Description of the serial (ASCII) protocol:
+   https://github.com/panStamp/panstamp/wiki/Modem%20and%20serial%20protocol
+
+5. aesencryption : use of the hadware AES-128 encryption engine available
+   on the CC430 MCU (panStamp NRG only).
+
+6. ctrencryption : CTR-cypher algorithm on top of the basic AES-128 encryption
+   (panStamp NRG only).
