dfu-programmer is an implementation of the Device Firmware Upgrade class
USB driver that enables firmware upgrades for various USB enabled (with the
correct bootloader) Atmel chips. This program was created because the
Atmel "FLIP" program for flashing devices does not support flashing via USB
on Linux, and because standard DFU loaders do not work for Atmel's chips.
Check out the Atmel website for more information. They are kind enough to
provide generally correct specifications this implementation is based on.
The project website is http://dfu-programmer.github.io and you can
use that to check for updates.

Simple install procedure for Unix/Linux/MAC
===========================================
 % tar -xzf dfu-programmer-<version>.tar.gz # unpack the sources
 -- or --
 % git clone https://github.com/dfu-programmer/dfu-programmer.git
 % cd dfu-programmer # change to the top-level directory
 [ If the source was checked-out from GitHub, run the following command.
 You may also need to do this if your libusb is in a non-standard location,
 or if the build fails to find it for some reason. This command requires
 that autoconf is installed (sudo apt-get install autoconf) ]
 % ./bootstrap.sh # regenerate base config files
 [ Optionally you can add autocompletion using the dfu_completion file,
 and possibly instructions provided after running the ./bootstrap command ]
 % ./configure # regenerate configure and run it
 [ Optionally you can specify where dfu-programmer gets installed
 using the --prefix= option to the ./configure command. See
 % ./configure --help for more details. ]
 [ By default the build process will use libusb-1.0 if available.
 It tries to auto-discover the library, falling back to the older
 libusb if libusb-1.0 is not available. This process is not entirely
 reliable and may decide that libusb-1.0 is available when in fact
 it is not. You can select libusb using --disable-libusb_1_0. If
 usb library is not available try getting libusb-1.0-0-dev ]
 % make # build dfu-programmer
 [ Become root if necessary ]
 % make install # install dfu-programmer
Build procedure for Windows
===========================
 Building Windows apps from source is never quite as simple ...
 Firstly you need to have MinGW and MSys with developer tools.
 Get them from http://sourceforge.net/projects/mingw/files/
 The windows build uses the libusb-win32 library, which is a
 port of libusb 0.1. For convenience these files are included
 with this distribution, located in the windows sub-directory.
 You need to copy these files to your MinGW install directory
 if they are not already there:
 windows/usb.h -> {path-to-mingw}/include/usb.h
 windows/libusb.a -> {path-to-mingw}/lib/libusb.a
 Open the MinGW shell window and change to the dfu-programmer folder.
 Note that C:\dir is accessed in MinGW using the path /c/dir
 [ If the source was checked-out from GitHub, run the following command ]
 $ ./bootstrap.sh
 $ ./configure --disable-libusb_1_0
 $ make
 The executable will be built in the dfu-programmer/src folder.
Windows Driver Files
====================
Atmel's FLIP programmer also uses libusb-win32, so we use the same
library here and take advantage of Atmel's official certified driver
set. The windows driver files can be downloaded as a separate zip file
dfu-prog-usb-x.x.x.zip
