+README
+======
+
+This README file discusses the port of NuttX to the MT-DB-X3 development
+board from MattairTech.  This board may host a variety of 64-pin AVR XMega
+part.  This port was specifically performed using the ATXmega384c3.
+
+See the MattairTech website for further information about the MT-DB-X3:
