+  Graph
+ 
+ A simple example of communication from the Arduino board to the computer:
+ the value of analog input 0 is sent out the serial port.  We call this "serial"
+ communication because the connection appears to both the Arduino and the
+ computer as a serial port, even though it may actually use
+ a USB cable. Bytes are sent one after another (serially) from the Arduino
+ to the computer.
+ 
+ You can use the Arduino serial monitor to view the sent data, or it can
+ be read by Processing, PD, Max/MSP, or any other program capable of reading 
+ data from a serial port.  The Processing code below graphs the data received 
+ so you can see the value of the analog input changing over time.
+ 
+ The circuit:
+ Any analog input sensor is attached to analog in pin 0.

+// -Address Arduino issue 509 :: Portability of ArduinoISP
+// http://code.google.com/p/arduino/issues/detail?id=509
+//
+// October 2010 by Randall Bohn
+// - Write to EEPROM > 256 bytes
+// - Better use of LEDs:
+// -- Flash LED_PMODE on each flash commit
+// -- Flash LED_PMODE while writing EEPROM (both give visual feedback of writing progress)
+// - Light LED_ERR whenever we hit a STK_NOSYNC. Turn it off when back in sync.
+// - Use pins_arduino.h (should also work on Arduino Mega)
+//
+// October 2009 by David A. Mellis
+// - Added support for the read signature command
+// 
+// February 2009 by Randall Bohn
+// - Added support for writing to EEPROM (what took so long?)
+// Windows users should consider WinAVR's avrdude instead of the
+// avrdude included with Arduino software.
+//
+// January 2008 by Randall Bohn
+// - Thanks to Amplificar for helping me with the STK500 protocol

+This directory contains the Optiboot small bootloader for AVR
+microcontrollers, somewhat modified specifically for the Arduino
+environment.
+
+Optiboot is more fully described here: http://code.google.com/p/optiboot/
+and is the work of Peter Knight (aka Cathedrow), building on work of Jason P
+Kyle, Spiff, and Ladyada.  Arduino-specific modification are by Bill
+Westfield (aka WestfW)
+
+Arduino-specific issues are tracked as part of the Arduino project
+at http://code.google.com/p/arduino
+
+
+------------------------------------------------------------
+Building optiboot for Arduino.
+
+Production builds of optiboot for Arduino are done on a Mac in "unix mode"
+using CrossPack-AVR-20100115.  CrossPack tracks WINAVR (for windows), which
+is just a package of avr-gcc and related utilities, so similar builds should
+work on Windows or Linux systems.
+
+One of the Arduino-specific changes is modifications to the makefile to
+allow building optiboot using only the tools installed as part of the
+Arduino environment, or the Arduino source development tree.  All three
+build procedures should yield identical binaries (.hex files) (although
+this may change if compiler versions drift apart between CrossPack and
+the Arduino IDE.)
+
+
+Building Optiboot in the Arduino IDE Install.
+
+Work in the .../hardware/arduino/bootloaders/optiboot/ and use the
+"omake <targets>" command, which just generates a command that uses
+the arduino-included "make" utility with a command like:
+    make OS=windows ENV=arduino <targets>
+or  make OS=macosx ENV=arduino <targets>
+On windows, this assumes you're using the windows command shell.  If
+you're using a cygwin or mingw shell, or have one of those in your
+path, the build will probably break due to slash vs backslash issues.
+On a Mac, if you have the developer tools installed, you can use the
+Apple-supplied version of make.
+The makefile uses relative paths ("../../../tools/" and such) to find
+the programs it needs, so you need to work in the existing optiboot
+directory (or something created at the same "level") for it to work.
+
+
+Building Optiboot in the Arduino Source Development Install.
+
+In this case, there is no special shell script, and you're assumed to
+have "make" installed somewhere in your path.
+Build the Arduino source ("ant build") to unpack the tools into the
+expected directory.
+Work in Arduino/hardware/arduino/bootloaders/optiboot and use
+    make OS=windows ENV=arduinodev <targets>
+or  make OS=macosx ENV=arduinodev <targets>
+
+
+Programming Chips Using the _isp Targets
+
+The CPU targets have corresponding ISP targets that will actuall
+program the bootloader into a chip. "atmega328_isp" for the atmega328,
+for example.  These will set the fuses and lock bits as appropriate as
+well as uploading the bootloader code.
+
+The makefiles default to using a USB programmer, but you can use
+a serial programmer like ArduinoISP by changing the appropriate
+variables when you invoke make:
+
+   make ISPTOOL=stk500v1 ISPPORT=/dev/tty.usbserial-A20e1eAN  \
+        ISPSPEED=-b19200 atmega328_isp
+
+The "atmega8_isp" target does not currently work, because the mega8
+doesn't have the "extended" fuse that the generic ISP target wants to
+pass on to avrdude.  You'll need to run avrdude manually.
+
+
+Standard Targets
+
+I've reduced the pre-built and source-version-controlled targets
+(.hex and .lst files included in the git repository) to just the
+three basic 16MHz targets: atmega8, atmega16, atmega328.

+    \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.

+        // Disable interrupts.
+

+    
+        eeprom_busy_wait ();
+

+
+        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
