+# PATHS YOU NEED TO SET UP
+#
+# We need to worry about three different sorts of file:
+#
+# 1. Things which are included in this distribution e.g. ard-reset-arduino
+#    => ARDMK_DIR - Where the *.mk files are stored
+#    => ARDMK_PATH - Where the ard-reset-arduino script is stored
+#
+# 2. Things which are always in the Arduino distribution e.g.
+#    boards.txt, libraries, &c.
+#    => ARDUINO_DIR
+#
+# 3. Things which might be bundled with the Arduino distribution, but
+#    might come from the system. Most of the toolchain is like this:
+#    on Linux it's supplied by the system.
+#    => AVR_TOOLS_DIR
+#
+# Having set these three variables, we can work out the rest assuming
+# that things are canonically arranged beneath the directories defined
+# above.
+#
+# On the Mac you might want to set:
+#
+#   ARDUINO_DIR   = /Applications/Arduino.app/Contents/Resources/Java
+#   ARDMK_DIR     = /usr/local
+#
+# On Linux, you might prefer:
+#
+#   ARDUINO_DIR   = /usr/share/arduino
+#   ARDMK_DIR     = /usr
+#   AVR_TOOLS_DIR = /usr
+#
+# You can either set these up in the Makefile, or put them in your
+# environment e.g. in your .bashrc
+#
+# If you don't specify these, we can try to guess, but that might not work
+# or work the way you want it to.
+#
+# If you don't install the ard-reset-arduino binary to /usr/local/bin, but
+# instead copy them to e.g. /home/mjo/arduino.mk/bin then set
+#   ARDMK_PATH = /home/mjo/arduino.mk/bin
+#
+# If you'd rather not see the configuration output, define ARDUINO_QUIET.

+# DEPENDENCIES

+# The Perl programs need a couple of libraries:
+#    Device::SerialPort
+#
+########################################################################
+#
+# STANDARD ARDUINO WORKFLOW
+#
+# Given a normal sketch directory, all you need to do is to create
+# a small Makefile which defines a few things, and then includes this one.
+#
+# For example:
+#
+#       ARDUINO_LIBS = Ethernet SPI
+#       BOARD_TAG    = uno
+#       MONITOR_PORT = /dev/cu.usb*
+#
+#       include /usr/share/arduino/Arduino.mk
+#
+# Hopefully these will be self-explanatory but in case they're not:
+#
+#    ARDUINO_LIBS - A list of any libraries used by the sketch (we
+#                   assume these are in $(ARDUINO_DIR)/hardware/libraries
+#                   or your sketchbook's libraries directory)
+#
+#    MONITOR_PORT - The port where the Arduino can be found (only needed
+#                   when uploading)
+#
+#    BOARD_TAG    - The tag for the board e.g. uno or mega
+#                   'make show_boards' shows a list
+#
+# If you have your additional libraries relative to your source, rather
+# than in your "sketchbook", also set USER_LIB_PATH, like this example:
+#
+#        USER_LIB_PATH := $(realpath ../../libraries)
+#
+# If you've added the Arduino-Makefile repository to your git repo as a
+# submodule (or other similar arrangement), you might have lines like this
+# in your Makefile:
+#
+#        ARDMK_DIR := $(realpath ../../tools/Arduino-Makefile)
+#        include $(ARDMK_DIR)/arduino-mk/Arduino.mk
+#
+# In any case, once this file has been created the typical workflow is just
+#
+#   $ make upload
+#
+# All of the object files are created in the build-{BOARD_TAG} subdirectory
+# All sources should be in the current directory and can include:
+#  - at most one .pde or .ino file which will be treated as C++ after
+#    the standard Arduino header and footer have been affixed.
+#  - any number of .c, .cpp, .s and .h files
+#
+# Included libraries are built in the build-{BOARD_TAG}/libs subdirectory.
+#
+# Besides make upload, there are a couple of other targets that are available.
+# Do make help to get the complete list of targets and their description
+#
+########################################################################
+#
+# SERIAL MONITOR
+#
+# The serial monitor just invokes the GNU screen program with suitable
+# options. For more information see screen (1) and search for
+# 'character special device'.
+#
+# The really useful thing to know is that ^A-k gets you out!
+#
+# The fairly useful thing to know is that you can bind another key to
+# escape too, by creating $HOME{.screenrc} containing e.g.
+#
+#    bindkey ^C kill
+#
+# If you want to change the baudrate, just set MONITOR_BAUDRATE. If you
+# don't set it, it tries to read from the sketch. If it couldn't read
+# from the sketch, then it defaults to 9600 baud.
+#
+########################################################################
+#
+# ARDUINO WITH ISP
+#
+# You need to specify some details of your ISP programmer and might
+# also need to specify the fuse values:
+#
+#     ISP_PROG	   = stk500v2
+#     ISP_PORT     = /dev/ttyACM0
+#
+# You might also need to set the fuse bits, but typically they'll be
+# read from boards.txt, based on the BOARD_TAG variable:
+#
+#     ISP_LOCK_FUSE_PRE  = 0x3f
+#     ISP_LOCK_FUSE_POST = 0xcf
+#     ISP_HIGH_FUSE      = 0xdf
+#     ISP_LOW_FUSE       = 0xff
+#     ISP_EXT_FUSE       = 0x01
+#
+# You can specify to also upload the EEPROM file:
+#     ISP_EEPROM   = 1
+#
+# I think the fuses here are fine for uploading to the ATmega168
+# without bootloader.
+#
+# To actually do this upload use the ispload target:
+#
+#    make ispload
+#
+#
+########################################################################
+#
+# ALTERNATIVE CORES
+#
+# To use alternative cores for platforms such as ATtiny, you need to
+# specify a few more variables, depending on the core in use.
+#
+# The HLT (attiny-master) core can be used just by specifying
+# ALTERNATE_CORE, assuming your core is in your ~/sketchbook/hardware
+# directory. For example:
+#
+# ISP_PORT           = /dev/ttyACM0
+# BOARD_TAG          = attiny85
+# ALTERNATE_CORE     = attiny-master
+#
+# To use the more complex arduino-tiny and TinyCore2 cores, you must
+# also set ARDUINO_CORE_PATH and ARDUINO_VAR_PATH to the core
+# directory, as these cores essentially replace the main Arduino core.
+# For example:
+#
+# ISP_PORT          = /dev/ttyACM0
+# BOARD_TAG         = attiny85at8
+# ALTERNATE_CORE    = arduino-tiny
+# ARDUINO_VAR_PATH  = ~/sketchbook/hardware/arduino-tiny/cores/tiny
+# ARDUINO_CORE_PATH = ~/sketchbook/hardware/arduino-tiny/cores/tiny
+#
+# or....
+#
+# ISP_PORT          = /dev/ttyACM0
+# BOARD_TAG         = attiny861at8
+# ALTERNATE_CORE    = tiny2
+# ARDUINO_VAR_PATH  = ~/sketchbook/hardware/tiny2/cores/tiny
+# ARDUINO_CORE_PATH = ~/sketchbook/hardware/tiny2/cores/tiny
