+____________________________________________________________
+
+  - WiiYourself! - native C++ Wiimote library  v1.15
+    (c) gl.tter 2007-10 - http://gl.tter.org
+____________________________________________________________
+
+History:
+
+What's new since 1.01a? - Main Features (see ReadMe & full history for details)
+
+    + Balance Board support with automatic offset removal.
+
+    + Seemingly solid MotionPlus support.
+
+    + Library no longer includes project files - just add wiimote.cpp &
+      header to your project (avoids all build-settings releated issues)
+    
+    + better MinGW support:  (thanks Elmo)
+      adds functional _ASSERT/TRACE/WARN/DEEP_TRACE macros
+          non-MSYS dependent build option via 'make_mingw.bat'.
+          Demo builds & works under MinGW.
+    
+    + new Python wrapper (by Robert Xiao, see 'Python' folder for details)
+    
+    + library now compiles on Borland (thanks Griff - demo not tested).
+    
+    + many fixes, connections should be more reliable.
+    
+    + join my mailing list to give feedback, share ideas & stay informed:
+        http://gl.tter.org/mailman/listinfo/wiiyourself_gl.tter.org
+
+1.15 Final:
+    + fixed MotionPlus detection on stacks that require HID writes!
+    + Balance Board corner weight values have been quartered (.Total remains
+       unchanged).  The non-raw corner weight incorrectly reported 4x their
+       real value.
+    + Wiimote calibration info is more reliably received (it may not have
+       arrived in many instances)
+    + exposed a partially-unique device ID (wiimote::UniqueID).  This 64bit
+       number is set during the Connect() call, and is derived from the
+       device-specific calibration values.  It's therefore not guaranteed to
+       be truly unique (several devices may conceivably hold the same calibration
+       values).  However in practice it is likely to be unique between a
+       few wiimotes, so it can be used to eg. assign a particular wiimote to the
+       same player every time.
+    + internal: made the HID report output queue fixed-size to remove any
+                 glitches from frequent dynamic memory allocation (thanks
+                 Steve).  The old STL-queue based code can still be reenabled
+                 by defining USE_DYNAMIC_HIDQUEUE.
+
+1.15 RC2:
+    + added Python wrapper by Robert Xiao - you can now use WiiYourself! with
+       Python! (thanks Robert)
+    + hopefully fixed MotionPlus connection problems! (send report to my
+       mailing list)
+
+    + added virtual event-change notifier to the wiimote object (thanks Robert
+       Xio) - works the same as external callbacks.  To use, derive your own
+       class from the wiimote object and override ChangedNotifier()
+
+    + changed the way callbacks work:
+    
+      in previous versions, it was OK to access the wiimote object's state
+        from callbacks.  This required an internal RefreshState() call just
+        before the callback function is executed - but this could then change
+        the internal state unexpectedly, so values could change in polling
+        loops even between the app's own RefreshState() calls.
+        
+      to correct this, the callback functions now get a read-only copy
+       of the newest state passed in, you should only access this copy as
+       state in the wiimote object is likely out-of-date.
+       
+      In short, the wiimote object's exposed state is now _only_ refreshed
+       by the application, not by callbacks.
+       
+      (this also solved Motion+ connection and disabling failures).
+      
+    + added new change event 'CONNECTED'
+    
+      the demo previously used callbacks to set most of its report types, but
+       it also set them once shortly after connecting the wiimote, and this could
+       cause it to set the wrong one, breaking extension data.  Instead it now
+       uses the CONNECTED event in the callback.  It's best to only set these
+       in one place.
+       
+1.15 RC:
+    + fixed missing Balance Board calibration values for the 34kg category
+       (thanks Benjamin Lassort).
+    
+    + fixed Wiimote disconnecting in certain scenarios (ReportType wasn't
+       initialised, and this could sometimes be sent to the 'mote, causing
+       it to disconnect - thanks Robert Xiao).
+       
+    + minor changes to support Robert Xiao's WiiYourself! Python Wrapper!
+      (next release).
+
+1.14 BETA:
+	  - added new state & callback event: bBatteryDrained / BATTERY_DRAINED
+	     this is sent went the wiimote signals that the batteries are nearly
+	     empty.
+	  - added MotionPlus extension events (ie. for extensions plugged into it):
+	  	  MOTIONPLUS_EXTENSION_CONNECTED
+	  	  MOTIONPLUS_EXTENSION_DISCONNECTED
+	  	 wiimote::MotionPlusHasExtension()
+	  	 wiimote::DisableMotionPlus()
+	  	 wiimote::EnableMotionPlus()
+         
+         (apps can now decide if they want to disable the MotionPlus to read the
+         extension instead, see demo for an example)
+         
+         ** however **, MotionPlus disabling isn't reliable at the moment (it
+         rarely works), and so extension connected to an already enabled plus
+         rarely are activated.  Could use some help on this one.
+	     
+1.13 BETA:
+      + ** BALANCE BOARDS no longer require setting a report type! **
+        there is only one type for it, and this is now set automatically.
+        
+      + 'At Rest' offset removal added (currently only for Balance Boards).
+         this reads the current analogue sensor values after a Connect() call,
+         and then subtracts them from future values, to remove any unwanted
+         offsets (currently ~ +- 0-2.5kg with Balance Boards).  'raw' values
+         are not affected.
+         
+         If the device was not at rest during Connect(), then the app can
+          remove the current offsets manually via CalibrateAtRest().
+          
+      + ** PRELIMINARY MOTION PLUS SUPPORT! **
+      
+        Motion Plus does not report itself until queried, so it's currently
+        queried every second.  If detected, it is activated and is reported
+        like any other extension.  Note that extensions plugged into the
+        MotionPlus itself can't currently be used at the same time (it's not
+        known if this is even possible).  Right now you need to unplug the
+        MotionPlus to use another extension (I will add some way to toggle
+        the MotionPlus so that another extensions becomes available again)
+        in the next release.
+        
+        According to this interview with the MotionPlus designers
+        
+        there are two gyro sensitivity modes, but this has not been reverse
+        engineered yet.  Also I'm not 100% certain of the correctness of the
+        values (although they seem right), or their actual scale (ie. how many
+        degrees rotations per second do the float values actually represent)?
+        
+      + the Demo has been updated for both devices.
+      + ReadMe has been updated with new relevant info.
+        
+1.12 BETA:
+      + ** REMOVED ALL LIBRARY PROJECTS **
+         instead just add wiimote.cpp to your application and include the header
+         as before (this removes all build/project related-problems, like matching
+         the runtime/Unicode settings etc).
+      
+      + Balance Board is now working (thanks to Akihiko's donation of a board!)
+      + added wiimote::IsBalanceBoard() (Balance Boards are detected as wiimotes
+         with a permanent BALANCE_BOARD extension).
+         NOTE: Balance Boards require the IN_BUTTONS_BALANCE_BOARD report type
+               (see demo).
+      + changed some of the wiimote_state extension enums to ID a wider variety.
+      + no more invalid acceleration values from devices that don't support it.
+      + fixed some project settings.
+      
+1.11 BETA:
+      + new way to detect extensions (supposedly works on all of them, including
+         wireless Nunchuks) - only tested on stock Nunchuk.
+      + longer sleep after SetReportType (may help data not being reported).
+
+1.1 BETA:
+      + beta Balance Board support!
+      + better MinGW support:  (thanks Elmo)
+          adds functional _ASSERT/TRACE/WARN/DEEP_TRACE macros
+          non-MSYS dependent build option via 'make_mingw.bat'.
+          Demo builds & works under MinGW.
+      + directory reorganisation:
+            - Each compiler has own project dir (VC2005/VC2005/MinGW),
+              and equivialent lib/ sudir.
+      + now ships with working VC2005 SP1 / VC2008 / MinGW libraries
+         (and MinGW DLL).
+      + library now compiles on Borland (thanks Griff) - demo may not.
+
+1.01a: (1.01 had incorrect version defines)
+      + extensions now work when already connected before Connect(),
+         & also when an EXT SetReportType() is used initially.
+      + ** renamed wiimote_state::IR::dot::bVisible to 'bVisible'. **
+      + Disconnect() now waits for its threads to exit.
+      +  made TRACE/WARN macros VC2005+ specific (as earlier VC versions don't
+         support variable arg macros).
+      + corrected wiimote.h Connect() comments (wiimote selection is 1-based,
+         not 0-based)
+
+1.00:
+    + ** major bug fix, write buffer was abused. ** might have caused various
+         problems.
+    + ** added delay to EnableIR(), fixed IR init problems for those that
+         had them (thanks Cameron) **.  if you had to use your own delays
+         to get things to work, try removing them now.
+    + wiimote_state::classic_controller::buttons::TriggerL() / R were reversed
+       (thanks Vico).
+    + patch & Makefile for MSYS / MinGW (thanks Dario).
+    + updated ReadMe.
+
+0.99b:
+    + added support for the Guitar Hero controller (thanks Morgan).
+       It's just a Classic Controller with a different ID and is read the same,
+       but can be differentiated via wiimote_state::extension_type::CLASSIC_GUITAR.
+
+0.96b:
+    + fix ClassicButtonNameFromBit[]
+    + fix WIIYOURSELF_VERSION_MINOR2
+
+0.95b:
+    + Classic Controller button fixes (thanks Farshid).
+    + sightly longer Sleep() in Reset() - hopefully fixes some reports of
+       wiimote acceleration values not working.
+    
+0.94b:
+    + deadzones weren't working.
+    
+0.93b:
+    + ** compiled libs are now stored in /libs **
+    + ** up to 4 dots are now available in every IR mode **
+    + some 'state_change_flags' weren't quite generated correctly.
+    - removed 'wiimote_state::polling' flags (redundant, flags are already
+       returned via RefreshState()).
+    + various internal improvements
+    
+0.92b:
+    ** Polling changes **
+      - now need to call RefreshState() once before each polling pass (see
+         header comments & demo). this was done to synchronise the threaded
+         state updates, so that data integrity is guaranteed.
+    ** Callback changes **
+      - combined 'wiimote_state_changed' and 'extension_state_changed' flags
+         into 'state_change_flags
+      - removed 'ExtensionChangedCallback' (only a single callback is used now)
+      - added 'CallbackTriggerFlags' to minimize callback overhead
+       (see header comments & demo)
+    + added Reset() (see header comments)
+    + button mask TRIGGER is now _B
+    
+    Demo: removed 'wiimote2' line (debug leftover)
+
+0.82b:
+    ** code/demo failed pre-XP (HID writes require XP+).  code now detects
+        HID write support dynamically. **
+    + tidied code & surpressed redundant warning (or just enable C++ exceptions).
+    + Improved debug output (mainly DEEP_TRACE)
+    + Connect() can now take (and defaults to) 'FIRST_AVAILABLE' as the wiimote
+      index (see header comments).
+    + 'wiimote_sample' is now auto-cleared on construction
+    + Adjusted max 'theoretical' raw IR coord values (1023x767) to largest
+       actually observed, to output full 0-1 float range.
+    + **Inverted** IR X float coord to match traditional 'left = 0' convention
+       (raw coords unaffected for now).
+    + Added state recording ability to aid state/motion analysis.  See RecordState();
+    - removed RequestBatteryUpdate() (battery level is now periodically refreshed)
+    - disabled ...CALIBRATION_CHANGED flags (not useful)
+    
+    Demo  : should now work pre-XP.
+    ReadMe: added Wiimote/PC installation notes (MS stack is especially tricky).
+
+0.81b:
+    + connection loss is now detected (via failed writes)
+      + ConnectionWasLost() added
+    + report modes renamed for clarity.
+    + Connect(): added 'force_hidwrites' (for testing only).
+    + Extension connections now seem to be reliable.
+    + Battery is now periodically refreshed (also used for loss detection)
+    + 'BatteryRaw' was set incorrectly
+    + added 'wiimote::ClassicButtonNameFromBit[]'
+
+    + Demo   : Classic Controller data shown.
+    + Demo   : IR dot sizes now reported when possible (only if extension 
+               data isn't requested as they're not available then).
+            
+    + License: 'no harm' clause added.
+    + ReadMe : added build notes etc.
+
+0.1b:
+    First release.

+
+     - WiiYourself! - native C++ Wiimote library  v1.15
+       (c) gl.tter 2007-10 - http://gl.tter.org
+__________________________________________________________________
+
+This marks the likely-final release of my free & fully-featured
+ Wiimote native C++ library for Windows.
+
+Originally based on Brian Peek's 'Managed Wiimote Library'
+ (http://blogs.msdn.com/coding4fun/archive/2007/03/14/1879033.aspx)
+ I then rewrote and extended it considerably.
+
+There's no documentation - check Brian's article for a good
+overview and general 'Wiimote with Windows' info - but the
+source code has extensive comments, and the demo app should help
+you make sense of it all.  Any questions, join my mailing list
+(below).
+
+Check License.txt for the (few) conditions of use, and
+ History.txt for important changes from previous versions.
+_____
+
+Notes:
+
+  - the library consists only of wiimote.cpp & wiimote.h.  Simply add
+     them to your project and include the header.
+
+  - VC 2005 & 2008 projects, and a MSYS makefile for MinGW for the
+     demo program are included.
+  
+  -	for MSYS:
+        at the MSYS prompt type:  make -f Makefile.MSYS
+         (it will create a folder named MinGW whith the binaries
+          and proper folder structure)
+        
+  - The Windows Driver Development Kit (WDK or DDK) is required to
+     build (for the HID API).  It's a free download from MS page
+     (no need to register).  Currently it's found here (or search
+     for it on microsoft.com):
+  
+     'Windows Driver Kit (WDK) 7.1.0'
+     http://www.microsoft.com/whdc/DevTools/WDK/WDKpkg.mspx
+
+    Unfortunately it changes frequently so the instructions below
+     may be wrong or incomplete.  Google or ask on my mailing
+     list for help if needed:
+     
+        - add its 'inc' and 'inc/api' dirs to your include paths
+         (make sure they are *above* other paths, ie. searched first)
+        
+        - add its 'lib/win7/i386' dir to your library paths.
+     
+    You can also use earlier versions known as the 'DDK'.  The parts
+     of the HID API I use haven't changed in a long time.  These paths
+     are usually used:
+      
+        - add 'inc/wxp' dir to your include paths (*above* others)
+        - add 'lib/wxp/i386' to your library paths.
+      
+    Notes:
+      - do _not_ add any 'STL' paths from the WDK/DDK as they can cause
+         build problems.
+      - the order of your include paths can be important.  If you placed
+         them above the paths and are still getting compilation errors,
+         try moving them around.
+  
+  - The library is Unicode-ready via <tchar.h> (see demo project).
+  
+  - if you're not using VC you need to link with these libraries:
+        setupapi.lib
+        winmm.lib
+        hid.lib     (from the DDK)
+__________________________  
+
+Wiimote installation notes:
+  
+  The Wiimote needs to be 'paired' (Bluetooth connected) with the
+   PC before you can install/use it.  Pressing 1 & 2 simultaneously
+   puts it into 'discoverable' mode for a few seconds (LEDs will
+   flash - the number of LEDs reflects the battery level).
+   
+  It will be detected as 'Nintendo RVL-CNT-01'.
+     
+  Stack-specific instructions:
+
+  - Windows' built-in Bluetooth stack:
+
+    1) open up the Bluetooth control panel.
+    2) press _and hold_ 1 & 2 on the wiimote (LEDs flash) until the
+       installation is complete (otherwise the wiimote usually times
+       out half-way through the procedure, and although it may seem
+       to have installed it's never 'connected' and doesn't work).
+    3) add a new device - it should find it. don't use a password.
+    4) when the installation is fully complete, let go of 1&2. The
+       Bluetooth panel should now show it 'connected'.
+    
+    if something goes wrong you need to uninstall it and try again.
+    
+    if you un-pair the wiimote later (see below), it seems you need
+     to remove and install it all over again to get it to work (if you
+     know a workaround, let me know).
+       
+  - Toshiba stack:
+
+    straight forward, press 1 & 2 on the Wiimote (you don't need to
+    hold them if you're quick) and click 'New Connection'.
+    
+    once found, you can pair it anytime again by right-clicking its
+     device icon (and pressing 1 & 2 as before) - you can also set up
+     a desktop shortcut that enters discovery mode immediately.
+
+  - Widcomm stack:
+
+    1) Open 'My Bluetooth Places'.
+    2) Press and hold 1 & 2 (until the process is complete).
+    3) Click 'View Devices in Range'.
+    4) Wiimote is detected as Nintendo RVL-CNT-01.
+    5) Select it, then click 'Bluetooth Setup Wizard'.
+    5) Click 'Skip' (no password).
+    6) Now it should be connected (you can let go of 1 & 2).
+
+    Troubleshooting:
+        - the device seems to be connected but the Demo can't find it
+          (CreateFile() fails with error 5 'Access Denied'),
+     or - it disconnects almost immediately after connection
+     or - asks for a password a few seconds after connection
+
+     Try uninstalling all HID devices from Device Manager, and then
+      redetecting them with 'Scan for hardware changes' (I had all
+      these problems and that fixed it for me).
+
+  - Other stacks
+  
+    similar to the above (contribute instructions?)
+    
+  
+  - Disconnect/un-pair to save power (any stack):
+
+    hold the Wiimote Power button for a few seconds - it automatically
+    unpairs itself, re-enters pairing mode for a few seconds
+    (flashing LEDs), then times out and (effecively) switches off.
+
+__________________________  
+
+Balance Boards notes:
+
+  Balance Boards are installed using the same procedure as wiimotes, by
+   holding the 'Sync' button in the battery compartment.  The Bluetooth
+   stack detectes them as 'Nintendo RVL-WBC-01'.
+
+  They report to the library as wiimotes, with a permanent BALANCE_BOARD
+   extension.  They only have one button (A), and no IR/Acceleration/Rumble
+   or Speaker support.  There is only one supported 'report type' so the
+   library sets this automatically (see the demo for details).
+   
+   You can detect them with the wiimote::IsBalanceBoard() call.
+   
+   The boards tested so far all report up to ~ +-2.5KB weight offsets even
+    where there is no weight placed on them (ie. 'at rest').  It is unknown
+    if this is normal sensor inaccuracy/drift, or if the calibration values
+    read from the board are interpreted incorrectly.  For now the library
+    automatically subtracts the first incoming sensor values after a Connect()
+    call from all future non-raw values (the raw values are never modified).
+    
+    The offsets used are exposed in wiimote_state::balance_board::AtRestKG.
+   
+    - if the board wasn't at rest during the Connect() call these offsets
+       will be wrong - the app can measure them manually (when the board
+       is at rest) by calling  wiimote::CalibrateAtRest().
+
+__________________________  
+
+MotionPlus notes:
+
+  Once activated it's reported like any other extension, but needs to be
+   manually enabled (see demo for an example):
+      - Test first if it's connected via MotionPlusConnected()
+      - Then call EnableMotionPlus()
+      - It will then replace any other extension connected to it, unil you
+         disable the Motion+ again with DisableMotionPlus().
+   
+  The speed values are believed to be correct.  The calibration values are not
+   yet understood, so the data is currently uncalibrated.  
+   
+  Some technical details are mentioned in this interview with the MotionPlus
+   hardware/software engineers:
+   http://uk.wii.com/wii/en_GB/software/iwata_asks_motionplus_volume_1_2162.html#top
