+    \code
+    #include <avr/io.h>
+    #include <avr/boot.h>
+    \endcode
+
+    The macros in this module provide a C language interface to the
+    bootloader support functionality of certain AVR processors. These
+    macros are designed to work with all sizes of flash memory.
+
+    Global interrupts are not automatically disabled for these macros. It
+    is left up to the programmer to do this. See the code example below. 
+    Also see the processor datasheet for caveats on having global interrupts 
+    enabled during writing of the Flash.
+
+    \note Not all AVR processors provide bootloader support. See your
+    processor datasheet to see if it provides bootloader support.
+
+    \todo From email with Marek: On smaller devices (all except ATmega64/128),
+    __SPM_REG is in the I/O space, accessible with the shorter "in" and "out"
+    instructions - since the boot loader has a limited size, this could be an
+    important optimization.
+
+    \par API Usage Example
+    The following code shows typical usage of the boot API.
+
+    \code
+    #include <inttypes.h>
+    #include <avr/interrupt.h>
+    #include <avr/pgmspace.h>
+    
+    void boot_program_page (uint32_t page, uint8_t *buf)
+    {
+        uint16_t i;
+        uint8_t sreg;
+
+        // Disable interrupts.
+
+        sreg = SREG;
+        cli();
+    
+        eeprom_busy_wait ();
+
+        boot_page_erase (page);
+        boot_spm_busy_wait ();      // Wait until the memory is erased.
+
+        for (i=0; i<SPM_PAGESIZE; i+=2)
+        {
+            // Set up little-endian word.
+
+            uint16_t w = *buf++;
+            w += (*buf++) << 8;
+        
+            boot_page_fill (page + i, w);
+        }
+
+        boot_page_write (page);     // Store buffer in flash page.
+        boot_spm_busy_wait();       // Wait until the memory is written.
+
+        // Reenable RWW-section again. We need this if we want to jump back
+        // to the application after bootloading.
+
+        boot_rww_enable ();
+
+        // Re-enable interrupts (if they were ever enabled).

+//    apparently obvious to someone trying to port it to another processor
+//    (for an example see original use of CDC_GetInterface - lame!)

+ *  Udp.cpp: Library to send/receive UDP packets.
+ *
+ * NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
+ * 1) UDP does not guarantee the order in which assembled UDP packets are received. This
+ * might not happen often in practice, but in larger network topologies, a UDP
+ * packet can be received out of sequence.
+ * 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
+ * aware of it. Again, this may not be a concern in practice on small local networks.
+ * For more information, see http://www.cafeaulait.org/course/week12/35.html

+
+  The xmega code mods make a considerable number of assumptions
+  about the pin number assignments (as defined here):
+
+  DEFAULT MAPPING ('DIGITAL_IO_PIN_SHIFT' NOT DEFINED)
+  ----------------------------------------------------
+  PORTD - digital 0-7
+  PORTC - digital 8-15
+  PORTE - digital 16-20
+  PORTR - digital 20-21 (built-in LED on PORTR pin 1, aka '21')
+  PORTA - analog 0-7, digital 22-29
+  PORTB - analog 8-11, digital 30-33
+
+  SPI is assumed to be on PORTC (pins 4-7)
+  Serial is implemented on PORTD, Serial2 on PORTC, both using pins 2,3 (no flow control)
+  PORTR pin 1 is assumed to be connected to an LED.  Pin 1 is the 'built-in' LED, defined
+  as 'LED_BUILTIN', and is active HIGH.
+
+  Your Mileage May Vary, depending on your board layout.  Some boards shift the
+  digital pin assignments by 2 so that digital I/O pin 0 is PORTD Rx, pin 13 is PORTC SCK, just
+  like the Arduino ATmega board.  Then they align the physical pins so that a regular Arduino shield
+  will work, and assign PORTD 0-1 to 2 different digital I/O pin numbers (such as 20 and 21).
+
+  To facilitate that specific change, uncomment the #define for 'DIGITAL_IO_PIN_SHIFT', below.
+  Alternately you can create a separate version of this file with a different variant name,
+  such as 'xmega-compat', with the #define uncommented, stored in an appropriately named directory.
+
+  ============================
+  HARDWARE SERIAL FLOW CONTROL
+  ============================
+
+  This version of the xmega Arduino startup+support files supports HARDWARE FLOW CONTROL on BOTH serial ports via
+  RTS (output) and CTS (input).  CTS is implemented as input from remote device's DTR.  RTS is implemented as DTR output.
+
+  To implement RTS/CTS, use definitions similar to the following in your version of this header file
+
+  NOTE: RTS(DTR) will be configured as an output, active low (high tells sender to stop sending data to the UART)
+        CTS will be configured as an input, active low (high stops data from being sent out via UART)
+
+  CTS high to low transition causes an interrupt that may result in serial I/O (for faster response time).
+
+  // RTS(DTR) as GPIO 0 (port D pin 0)
+  #define SERIAL_0_RTS_PORT_NAME PORTD
+  #define SERIAL_0_RTS_PIN_INDEX 0
+
+  // CTS as GPIO 1 (port D pin 1)
+  #define SERIAL_0_CTS_PORT_NAME PORTD
+  #define SERIAL_0_CTS_PIN_INDEX 1
+
+  use similar definitions for serial 1, aka 'SERIAL_1_CTS_PORT'
+
+  NOTE:  you can even use PORTA or PORTB pins for this, if you don't need to measure analog volts on those pins
