# Arduino-1.0 Makefile 
 | 
						|
#
 | 
						|
# written by olikraus@gmail.com
 | 
						|
#
 | 
						|
# Features:
 | 
						|
#   - boards.txt is used to derive parameters
 | 
						|
#   - All intermediate files are put into a separate directory (TMPDIRNAME)
 | 
						|
#   - Simple use: Copy Makefile into the same directory of the .ino file
 | 
						|
#
 | 
						|
# Limitations:
 | 
						|
#   - requires UNIX environment
 | 
						|
#   - TMPDIRNAME must be subdirectory of the current directory.
 | 
						|
#
 | 
						|
# Targets
 | 
						|
# 	all		build everything
 | 
						|
#	upload	build and upload to arduino
 | 
						|
#	clean	remove all temporary files (includes final hex file)
 | 
						|
