+/**
+ * A low-power-listening CC1000 radio stack.
+ *
+ * Radio logic is split between Csma (media-access control, low-power
+ * listening and general control) and SendReceive (packet reception and
+ * transmission). 
+ *
+ * CC1000RssiP (RSSI sharing), CC1000SquelchP (noise-floor estimation)
+ * and CC1000ControlP (radio configuration) provide supporting roles.
+ *
+ * This code has some degree of platform-independence, via the HplCC1000,
+ * RssiAdc and HplCC1000Spi interfaces which must be provided by the
+ * platform. However, these interfaces may still reflect some
+ * particularities of the mica2 hardware implementation.
