#	The required information is extracted out of the command line send by
#	arduinocdt
#
#
#	Usage:
#	1:	Place this script in:
#			/Users/[YOURUSERNAME]/.arduinocdt/packages/arduino/tools/avrdude/[VERSION]/bin
#	2:	Edit:
#			/Users/[YOURUSERNAME]/.arduinocdt/packages/arduino/hardware/avr/[VERSION]/platform.txt
#		Replace:
#			tools.avrdude.cmd.path={path}/bin/avrdude
#		With:
#			tools.avrdude.cmd.path={path}/bin/avrdude_wrapper.bat
#	3:	(re)start eclipse.
