This is a Makefile to build Arduino projects with make. It is based on Martin Oldfields Makefile and was adapted to support Arduino 1.0 and user libraries.
Here is an example Makefile that includes Arduino.mk
ARDUINO_DIR = /Applications/Arduino.app
USER_LIB_PATH = ~/Documents/Arduino/libraries
TARGET = CLItest
ARDUINO_LIBS = LiquidCrystal
USER_LIBS = MyLib
BOARD_TAG = uno
ARDUINO_PORT = /dev/cu.usb*
include /usr/local/share/Arduino.mk
Place it beside your .ino file and call make and make upload.
