26+ # Makefile for building Arduino projects outside of the Arduino environment

31+ # ----------
32+ # BOARD = mega
33+ # PORT = /dev/term/0
34+ # THIRD_PARTY_HARDWARE = /Arduino/hardware/Sanguino

37+ # include ../../Makefile.master
38+ # ----------
39+ #
40+ # Where:
41+ # BOARD : Arduino board type, from boards.txt
42+ # PORT : USB port
43+ # THIRD_PARTY_HARDWARE : Path to third party hardware folder
44+ # INC_DIRS : List pf directories containing header files
45+ # LIB_DIRS : List of directories containing library source
46+ #
47+ # Before using this Makefile you can adjust the following macros to suit
48+ # your environment, either by editing this file directly or by defining them in
49+ # the Makefile that includes this one, in which case they will override the
50+ # definitions below:
51+ # ARD_REV : Arduino software revision, e.g. 0017, 0018
52+ # ARD_HOME : installation directory of the Arduino software.
53+ # ARD_BIN : location of compiler binaries
54+ # AVRDUDE : location of avrdude executable
55+ # AVRDUDE_CONF : location of avrdude configuration file
56+ # PROGRAMMER : avrdude programmer type
57+ # MON_SPEED : serial monitor speed
58+ # EXTRA_FLAGS : any extra flags that should be passed to the compilers
59+ #
60+
61+ # Global configuration.
