+# How to include the library
+
+### Arduino Library Manager
+
+First install Arduino IDE version 1.6.2 or newer, then simply use the Arduino Library Manager to install the library.
+
+Please see the following page for instructions: <http://www.arduino.cc/en/Guide/Libraries#toc3>.
+
+### Manual installation
+
+First download the library by clicking on the following link: <https://github.com/felis/USB_Host_Shield_2.0/archive/master.zip>.
+
+Then uncompress the zip folder and rename the directory to "USB\_Host\_Shield\_20", as any special characters are not supported by the Arduino IDE.
+
+Now open up the Arduino IDE and open "File>Preferences". There you will see the location of your sketchbook. Open that directory and create a directory called "libraries" inside that directory.
+Now move the "USB\_Host\_Shield\_20" directory to the "libraries" directory.
+
+The final structure should look like this:
+
+* Arduino/
+    * libraries/
+        * USB\_Host\_Shield\_20/
+
+Now quit the Arduino IDE and reopen it.
+
+Now you should be able to go open all the examples codes by navigating to "File>Examples>USB\_Host\_Shield\_20" and then select the example you will like to open.
+
+For more information visit the following sites: <http://arduino.cc/en/Guide/Libraries> and <https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use>.
+
+# How to use the library
+
+### Documentation
+
+Documentation for the library can be found at the following link: <http://felis.github.com/USB_Host_Shield_2.0/>.
+
+### Enable debugging
+
+By default serial debugging is disabled. To turn it on simply change ```ENABLE_UHS_DEBUGGING``` to 1 in [settings.h](settings.h) like so:
+
+```C++
+#define ENABLE_UHS_DEBUGGING 1
+```
+
+### Boards
+
+Currently the following boards are supported by the library:
+
+* All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
+* Arduino Due, Intel Galileo, Intel Galileo 2, and Intel Edison
+    * Note that the Intel Galileo uses pin 2 and 3 as INT and SS pin respectively by default, so some modifications to the shield are needed. See the "Interface modifications" section in the [hardware manual](https://www.circuitsathome.com/usb-host-shield-hardware-manual) for more information.
+* Teensy (Teensy++ 1.0, Teensy 2.0, Teensy++ 2.0, and Teensy 3.x)
+    * Note if you are using the Teensy 3.x you should download this SPI library as well: <https://github.com/xxxajk/spi4teensy3>. You should then add ```#include <spi4teensy3.h>``` to your .ino file.
+* Balanduino
+* Sanguino
+* Black Widdow
+* RedBearLab nRF51822
+* Digilent chipKIT
+    * Please see: <http://www.circuitsathome.com/mcu/usb/running-usb-host-code-on-digilent-chipkit-board>.
+
+The following boards need to be activated manually in [settings.h](settings.h):
+
+* Arduino Mega ADK
+    * If you are using Arduino 1.5.5 or newer there is no need to activate the Arduino Mega ADK manually
+* Black Widdow
+
+Simply set the corresponding value to 1 instead of 0.
+
+### [Bluetooth libraries](BTD.cpp)
+
+The [BTD library](BTD.cpp) is a general purpose library for an ordinary Bluetooth dongle.
+This library make it easy to add support for different Bluetooth services like a PS3 or a Wii controller or SPP which is a virtual serial port via Bluetooth.
+Some different examples can be found in the [example directory](examples/Bluetooth).
+
+The BTD library also makes it possible to use multiple services at once, the following example sketch is an example of this:
+[PS3SPP.ino](examples/Bluetooth/PS3SPP/PS3SPP.ino).
+
+### [BTHID library](BTHID.cpp)
+
+The [Bluetooth HID library](BTHID.cpp) allows you to connect HID devices via Bluetooth to the USB Host Shield.
+
+Currently HID mice and keyboards are supported.
+
+It uses the standard Boot protocol by default, but it is also able to use the Report protocol as well. You would simply have to call ```setProtocolMode()``` and then parse ```HID_RPT_PROTOCOL``` as an argument. You will then have to modify the parser for your device. See the example: [BTHID.ino](examples/Bluetooth/BTHID/BTHID.ino) for more information.
+
+The [PS4 library](#ps4-library) also uses this class to handle all Bluetooth communication.
+
+For information see the following blog post: <http://blog.tkjelectronics.dk/2013/12/bluetooth-hid-devices-now-supported-by-the-usb-host-library/>.
+
+### [SPP library](SPP.cpp)
+
+SPP stands for "Serial Port Profile" and is a Bluetooth protocol that implements a virtual comport which allows you to send data back and forth from your computer/phone to your Arduino via Bluetooth.
+It has been tested successfully on Windows, Mac OS X, Linux, and Android.
+
+Take a look at the [SPP.ino](examples/Bluetooth/SPP/SPP.ino) example for more information.
+
+More information can be found at these blog posts:
+
+* <http://www.circuitsathome.com/mcu/bluetooth-rfcommspp-service-support-for-usb-host-2-0-library-released>
+* <http://blog.tkjelectronics.dk/2012/07/rfcommspp-library-for-arduino/>
+
+To implement the SPP protocol I used a Bluetooth sniffing tool called [PacketLogger](http://www.tkjelectronics.com/uploads/PacketLogger.zip) developed by Apple.
+It enables me to see the Bluetooth communication between my Mac and any device.
+
+### PS4 Library
+
+The PS4BT library is split up into the [PS4BT](PS4BT.h) and the [PS4USB](PS4USB.h) library. These allow you to use the Sony PS4 controller via Bluetooth and USB.
+
+The [PS4BT.ino](examples/Bluetooth/PS4BT/PS4BT.ino) and [PS4USB.ino](examples/PS4USB/PS4USB.ino) examples shows how to easily read the buttons, joysticks, touchpad and IMU on the controller via Bluetooth and USB respectively. It is also possible to control the rumble and light on the controller and get the battery level.
+
+Before you can use the PS4 controller via Bluetooth you will need to pair with it.
+
+Simply create the PS4BT instance like so: ```PS4BT PS4(&Btd, PAIR);``` and then hold down the Share button and then hold down the PS without releasing the Share button. The PS4 controller will then start to blink rapidly indicating that it is in paring mode.
+
+It should then automatically pair the dongle with your controller. This only have to be done once.
+
+For information see the following blog post: <http://blog.tkjelectronics.dk/2014/01/ps4-controller-now-supported-by-the-usb-host-library/>.
+
+Also check out this excellent Wiki by Frank Zhao about the PS4 controller: <http://eleccelerator.com/wiki/index.php?title=DualShock_4> and this Linux driver: <https://github.com/chrippa/ds4drv>.
+
+### PS3 Library
+
+These libraries consist of the [PS3BT](PS3BT.cpp) and [PS3USB](PS3USB.cpp). These libraries allows you to use a Dualshock 3, Navigation or a Motion controller with the USB Host Shield both via Bluetooth and USB.
+
+In order to use your Playstation controller via Bluetooth you have to set the Bluetooth address of the dongle internally to your PS3 Controller. This can be achieved by first plugging in the Bluetooth dongle and wait a few seconds. Now plug in the controller via USB and wait until the LEDs start to flash. The library has now written the Bluetooth address of the dongle to the PS3 controller.
+
+Finally simply plug in the Bluetooth dongle again and press PS on the PS3 controller. After a few seconds it should be connected to the dongle and ready to use.
+
+__Note:__ You will have to plug in the Bluetooth dongle before connecting the controller, as the library needs to read the address of the dongle. Alternatively you could set it in code like so: [PS3BT.ino#L20](examples/Bluetooth/PS3BT/PS3BT.ino#L20).
+
+For more information about the PS3 protocol see the official wiki: <https://github.com/felis/USB_Host_Shield_2.0/wiki/PS3-Information>.

+### Xbox Libraries
+
+The library supports both the original Xbox controller via USB and the Xbox 360 controller both via USB and wirelessly.
+
+#### Xbox library
+
+The [XBOXOLD](XBOXOLD.cpp) class implements support for the original Xbox controller via USB.
+
+All the information are from the following sites:
+
+* <https://github.com/torvalds/linux/blob/master/Documentation/input/devices/xpad.rst>
+* <https://github.com/torvalds/linux/blob/master/drivers/input/joystick/xpad.c>
+* <http://euc.jp/periphs/xbox-controller.ja.html>
+* <https://github.com/Grumbel/xboxdrv/blob/stable/PROTOCOL#L15>
+
+#### Xbox 360 Library
+
+The library support one Xbox 360 via USB or up to four Xbox 360 controllers wirelessly by using a [Xbox 360 wireless receiver](http://blog.tkjelectronics.dk/wp-content/uploads/xbox360-wireless-receiver.jpg).
+
+To use it via USB use the [XBOXUSB](XBOXUSB.cpp) library or to use it wirelessly use the [XBOXRECV](XBOXRECV.cpp) library.
+
+__Note that a Wireless controller can NOT be used via USB!__
+
+Examples code can be found in the [examples directory](examples/Xbox).
+
+Also see the following blog posts:
+
+* <http://www.circuitsathome.com/mcu/xbox360-controller-support-added-to-usb-host-shield-2-0-library>
+* <http://blog.tkjelectronics.dk/2012/07/xbox-360-controller-support-added-to-the-usb-host-library/>
+* <http://blog.tkjelectronics.dk/2012/12/xbox-360-receiver-added-to-the-usb-host-library/>
+
+All the information regarding the Xbox 360 controller protocol are form these sites:
+
+* <http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/UsbInfo>
+* <http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/WirelessUsbInfo>
+* <https://github.com/Grumbel/xboxdrv/blob/stable/PROTOCOL>
+
+#### Xbox ONE Library
+
+An Xbox ONE controller is supported via USB in the [XBOXONE](XBOXONE.cpp) class. It is heavily based on the 360 library above. In addition to cross referencing the above, information on the protocol was found at:
+
+* <https://github.com/quantus/xbox-one-controller-protocol>
+* <https://github.com/torvalds/linux/blob/master/drivers/input/joystick/xpad.c>
+* <https://github.com/kylelemons/xbox/blob/master/xbox.go>
+
+### [Wii library](Wii.cpp)
+
+The [Wii](Wii.cpp) library support the Wiimote, but also the Nunchuch and Motion Plus extensions via Bluetooth. The Wii U Pro Controller and Wii Balance Board are also supported via Bluetooth.
+
+First you have to pair with the controller, this is done automatically by the library if you create the instance like so:
+
+```C++
+WII Wii(&Btd, PAIR);
+```
+
+And then press 1 & 2 at once on the Wiimote or the SYNC buttons if you are using a Wii U Pro Controller or a Wii Balance Board.
+
+After that you can simply create the instance like so:
+
+```C++
+WII Wii(&Btd);
+```
+
+Then just press any button on the Wiimote and it will then connect to the dongle.
+
+Take a look at the example for more information: [Wii.ino](examples/Bluetooth/Wii/Wii.ino).
+
+Also take a look at the blog post:
+
+* <http://blog.tkjelectronics.dk/2012/08/wiimote-added-to-usb-host-library/>
+
+The Wii IR camera can also be used, but you will have to activate the code for it manually as it is quite large. Simply set ```ENABLE_WII_IR_CAMERA``` to 1 in [settings.h](settings.h).
+
+The [WiiIRCamera.ino](examples/Bluetooth/WiiIRCamera/WiiIRCamera.ino) example shows how it can be used.
+
+All the information about the Wii controllers are from these sites:
+
+* <http://wiibrew.org/wiki/Wiimote>
+* <http://wiibrew.org/wiki/Wiimote/Extension_Controllers>
+* <http://wiibrew.org/wiki/Wiimote/Extension_Controllers/Nunchuck>
+* <http://wiibrew.org/wiki/Wiimote/Extension_Controllers/Wii_Motion_Plus>
+* <http://wiibrew.org/wiki/Wii_Balance_Board>
+* The old library created by _Tomoyuki Tanaka_: <https://github.com/moyuchin/WiiRemote_on_Arduino> also helped a lot.
+
+### [PS Buzz Library](PSBuzz.cpp)
+
+This library implements support for the Playstation Buzz controllers via USB.
+
+It is essentially just a wrapper around the [HIDUniversal](hiduniversal.cpp) which takes care of the initializing and reading of the controllers. The [PSBuzz](PSBuzz.cpp) class simply inherits this and parses the data, so it is easy for users to read the buttons and turn the big red button on the controllers on and off.
+
+The example [PSBuzz.ino](examples/PSBuzz/PSBuzz.ino) shows how one can do this with just a few lines of code.
+
+More information about the controller can be found at the following sites:
+
+* http://www.developerfusion.com/article/84338/making-usb-c-friendly/
+* https://github.com/torvalds/linux/blob/master/drivers/hid/hid-sony.c
+
+# Interface modifications
+
+The shield is using SPI for communicating with the MAX3421E USB host controller. It uses the SCK, MISO and MOSI pins via the ICSP on your board.
+
+Note this means that it uses pin 13, 12, 11 on an Arduino Uno, so these pins can not be used for anything else than SPI communication!
+
+Furthermore it uses one pin as SS and one INT pin. These are by default located on pin 10 and 9 respectively. They can easily be reconfigured in case you need to use them for something else by cutting the jumper on the shield and then solder a wire from the pad to the new pin.
+
+After that you need modify the following entry in [UsbCore.h](UsbCore.h):
+
+```C++
+typedef MAX3421e<P10, P9> MAX3421E;
+```
+
+For instance if you have rerouted SS to pin 7 it should read:
+
+```C++
+typedef MAX3421e<P7, P9> MAX3421E;
+```
+
+See the "Interface modifications" section in the [hardware manual](https://www.circuitsathome.com/usb-host-shield-hardware-manual) for more information.
+
+# FAQ
+
+> When I plug my device into the USB connector nothing happens?
+
+* Try to connect a external power supply to the Arduino - this solves the problem in most cases.
+* You can also use a powered hub between the device and the USB Host Shield. You should then include the USB hub library: ```#include <usbhub.h>``` and create the instance like so: ```USBHub Hub1(&Usb);```.
+
+> When I connecting my PS3 controller I get a output like this:
+
+```
+Dualshock 3 Controller Enabled
+
+LeftHatX: 0 LeftHatY: 0 RightHatX: 0 RightHatY: 0
+LeftHatX: 0 LeftHatY: 0 RightHatX: 0 RightHatY: 0
+LeftHatX: 0 LeftHatY: 0 RightHatX: 0 RightHatY: 0
+LeftHatX: 0 LeftHatY: 0 RightHatX: 0 RightHatY: 0
+LeftHatX: 0 LeftHatY: 0 RightHatX: 0 RightHatY: 0
+```
+
+* This means that your dongle does not support 2.0+EDR, so you will need another dongle. Please see the following [list](https://github.com/felis/USB_Host_Shield_2.0/wiki/Bluetooth-dongles) for tested working dongles.
+
+> When compiling I am getting the following error: "fatal error: SPI.h: No such file or directory".
+
+* Please make sure to include the SPI library like so: ```#include <SPI.h>``` in your .ino file.

+ * 1. reset
+ * 2. GetDevDescr();
+ * 3a. If ACK, continue with allocating address, addressing, etc.
+ * 3b. Else reset again, count resets, stop at some number (5?).
+ * 4. When max.number of resets is reached, toggle power/fail
+ * If desired, this could be modified by performing two resets with GetDevDescr() in the middle - however, from my experience, if a device answers to GDD()
+ * it doesn't need to be reset again
+ * New steps proposal:
+ * 1: get address pool instance. exit on fail
+ * 2: pUsb->getDevDescr(0, 0, constBufSize, (uint8_t*)buf). exit on fail.
+ * 3: bus reset, 100ms delay
+ * 4: set address

+ *                                          Instance already in use, ignore it, try next driver.

+Please see <http://wiibrew.org/wiki/Wiimote#IR_Camera> for the complete capabilities of the Wii camera. The IR camera code was written based on the above website and with support from Kristian Lauszus.
+
+This library is large, if you run into memory problems when uploading to the Arduino, disable serial debugging.
+
+To enable the IR camera code, simply set ```ENABLE_WII_IR_CAMERA``` to 1 in [settings.h](settings.h).
+
+This library implements the following settings:
+
+* Report sensitivity mode: 00 00 00 00 00 00 90 00 41	 40 00	 Suggested by inio (high sensitivity)
+* Data Format: Extended mode (0x03).  Full mode is not working yet. The output reports 0x3e and 0x3f need tampering with
+	* In this mode the camera outputs x and y coordinates and a size dimension for the 4 brightest points.
+
+Again, read through <http://wiibrew.org/wiki/Wiimote#IR_Camera> to get an understanding of the camera and its settings.

+To test the Wiimote IR camera, you will need access to an IR source. Sunlight will work but is not ideal.
+The simpleist solution is to use the Wii sensor bar, i.e. emitter bar, supplied by the Wii system.

+This small sketch tests the USB host shield mass storage library.
+
+__Note:__ This will not run a Arduino Uno due to the limited ram available in the ATmega328p.
+
+The Arduino Mega (ATmega1280) and the Arduino Mega 2560 (ATmega2560) are confirmed to work with this test code.
+
+To compile this example you will need the following libraries as well:
+
+* [xmem2](https://github.com/xxxajk/xmem2)
+* [generic_storage FATfs](https://github.com/xxxajk/generic_storage)
+* [RTClib](https://github.com/xxxajk/RTClib)
+
+The following shield is recommended for larger projects: <https://www.rugged-circuits.com/new-products/quadram>.
+
+You may use the bundled [Makefile](Makefile) to compile the code instead of the Arduino IDE if you have problems or want a smaller binary. The master makefile is bundled as a submodule, but can also be downloaded manually at the following link: <https://github.com/xxxajk/Arduino_Makefile_master>.
+
+To download the USB Host library and all the needed libraries for this test.
+
+Run the following command in a terminal application:
+
+```
+git clone --recursive https://github.com/felis/USB_Host_Shield_2.0
+```
+
+If you want to update all the submodules run:
+
+```
+git submodule foreach --recursive git pull origin master
+```

+/*
+ * Mega + USB storage + optional DS1307 + optional expansion RAM + funky status LED,
+ * Includes interactive debug level setting, and supports hot-plug.
+ *
+ * IMPORTANT! PLEASE USE Arduino 1.0.5 or better!
+ * Older versions HAVE MAJOR BUGS AND WILL NOT WORK AT ALL!
+ * Use of gcc-avr and lib-c that is newer than the Arduino version is even better.
+ * If you experience random crashes, use make.
+ * The options that the IDE use can generate bad code and cause the AVR to crash.
+ *
+ * This sketch requires the following libraries:
+ * https://github.com/felis/USB_Host_Shield_2.0 Install as 'USB_Host_Shield_2_0'
+ * https://github.com/xxxajk/xmem2 Install as 'xmem', provides memory services.
+ * https://github.com/xxxajk/generic_storage provides access to FAT file system.
+ * https://github.com/xxxajk/RTClib provides access to DS1307, or fake clock.
+ *
+ * Optional, to use the Makefile (Recommended! See above!):

+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ *  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
