+Copyright (c) 2007, Jim Studt (original old version - many contributors since)
+refactored from C++ to C by Bernhard Tittelbach
+
+The latest version of this library may be found at:
+ http://www.pjrc.com/teensy/td_libs_OneWire.html
+
+OneWire has been maintained by Paul Stoffregen (paul@pjrc.com) since
+January 2010. At the time, it was in need of many bug fixes, but had
+been abandoned the original author (Jim Studt). None of the known
+contributors were interested in maintaining OneWire. Paul typically
+works on OneWire every 6 to 12 months. Patches usually wait that
+long. If anyone is interested in more actively maintaining OneWire,
+please contact Paul.
+
+Version 2.2:
+ Teensy 3.0 compatibility, Paul Stoffregen, paul@pjrc.com
+ Arduino Due compatibility, http://arduino.cc/forum/index.php?topic=141030
+ Fix DS18B20 example negative temperature
+ Fix DS18B20 example's low res modes, Ken Butcher
+ Improve reset timing, Mark Tillotson
+ Add const qualifiers, Bertrik Sikken
+ Add initial value input to crc16, Bertrik Sikken
+ Add target_search() function, Scott Roberts
+
+Version 2.1:
+ Arduino 1.0 compatibility, Paul Stoffregen
+ Improve temperature example, Paul Stoffregen
+ DS250x_PROM example, Guillermo Lovato
+ PIC32 (chipKit) compatibility, Jason Dangel, dangel.jason AT gmail.com
+ Improvements from Glenn Trewitt:
+ - crc16() now works
+ - check_crc16() does all of calculation/checking work.
+ - Added read_bytes() and write_bytes(), to reduce tedious loops.
+ - Added ds2408 example.
+ Delete very old, out-of-date readme file (info is here)
+
+Version 2.0: Modifications by Paul Stoffregen, January 2010:
+http://www.pjrc.com/teensy/td_libs_OneWire.html
+ Search fix from Robin James
+ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
+ Use direct optimized I/O in all cases
+ Disable interrupts during timing critical sections
+ (this solves many random communication errors)
+ Disable interrupts during read-modify-write I/O
+ Reduce RAM consumption by eliminating unnecessary
+ variables and trimming many to 8 bits
+ Optimize both crc8 - table version moved to flash
+
+Modified to work with larger numbers of devices - avoids loop.
+Tested in Arduino 11 alpha with 12 sensors.
+26 Sept 2008 -- Robin James
+http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
+
+Updated to work with arduino-0008 and to include skip() as of
+2007/07/06. --RJL20
+
+Modified to calculate the 8-bit CRC directly, avoiding the need for
+the 256-byte lookup table to be loaded in RAM. Tested in arduino-0010
+-- Tom Pollard, Jan 23, 2008
+
+Jim Studt's original library was modified by Josh Larios.
+
+Tom Pollard, pollard@alum.mit.edu, contributed around May 20, 2008
