+.Sh NAME
+.Nm bsd.arduino.mk
+.Nd build Arduino sketches with
+.Xr make 1
+.Sh SYNOPSIS
+.Fd "ARDUINO_MK_DIR=%%PREFIX%%/arduino-bsd-mk"
+.Fd ...
+.Fd .include\ "${ARDUINO_MK_DIR}/bsd.arduino.mk"
+.Sh DESCRIPTION
+The file
+.Pa bsd.arduino.mk
+is used to build Arduino sketches from the command line using
+.Xr make 1 .
+The goal is to efficiently build potentially complicated projects
+with simple Makefiles and completely bypass the Arduino graphical
+user interface.
+.Pp
+Modules that are part of the standard Arduino distribution along with
+modules that are part of referenced Arduino libraries (specified
+with the
+.Va ARDUINO_LIBS
+variable) are compiled once and stored in a library. Sketch modules
+are built as determined by
+.Xr make 1 .
+.Sh TARGETS
+.Bl -tag -width 12345678
+.It defines
+Dump out the defines specific to
+.Va ARDUINO_BOARD .
+.It flash
+Compile, link and run
+.Xr avrdude 1
+to program the target board.
+.It install
+An alias for flash.
+.It lint
+Run
+.Xr cppcheck 1
+on all of the source files.
+.It obj
+Create a build directory.
+.It objlink
+Create a symlink to the build directory.
+.It report
+Use
+.Xr avrdude 1
+to report the fuse settings.
+.It size
+Use
+.Xr avr-size 1
+to list section sizes and total size.
+.It tags
+Create or update a tags file by running
+.Xr ctags 1
+on
+.Va SRCS
+and
+.Va HFILES .
+.El
+.Sh REQUIRED VARIABLES
+These variables must be set:
+.Bl -tag -width 12345678
+.It Va TARGET
+The name of the sketch. If
+.Va SRCS
+is not defined then the sketch is built from
+.Va ${TARGET}.cpp
+or
+.Va ${TARGET}.ino .
+.It Va ARDUINO_BOARD
+The name of the board. This is important as the
+.Pa arduino-boards
+script uses it to set the defaults for
+.Va ARDUINO_CORE ,
+.Va ARDUINO_VARIANT ,
+.Va F_CPU
+and
+.Va MCU
+from the Arduino 
+.Pa boards.txt
+file.
+.It Va ARDUINO_MK_DIR
+The path to the arduino-bsd-mk installation directory.
+.El
+.Sh USEFUL VARIABLES
+It's frequently useful to set these variables:
+.Bl -tag -width 12345678
+.It Va SRCS
+A list of  .ino, .cpp and .c sources. This is used when
+the name of the module does not match
+.Va TARGET
+and when more than one source is used.
+.It Va ARDUINO_LIBS
+A list of Arduino libraries. Since these are searched by first
+looking in 
+.Va .CURDIR
+and then in the Arduino tree
+.Pa ( %%PREFIX%%/arduino/libraries )
+it's possible to use local libraries and to override standard Arduino
+libraries.
+.El
+.Sh PROGRAMMING OPTIONS
+.Bl -tag -width 12345678
+.It Va AVRDUDE_PORT
+The
+.Xr avrdude 1
+programmer port when the programmer is "arduino".
+This is passed with the 
+.Fl P
+flag.
+.It Va AVRDUDE_PROGRAMMER
+An
+.Xr avrdude 1
+programmer id string. The default this is set using
+.Pa boards.txt .
+.Pp
+When
+.Va AVRDUDE_PROGRAMMER
+is "arduino" 
+.Va AVRDUDE_PORT
+must be set using one of these methods:
+.Bl -bullet -offset indent -compact
+.It
+In your shell environment before running "make flash"
+.It
+With the make command line, e.g. "make flash \%AVRDUDE_PORT=/dev/ttyU3"
+.It
+In Makefile.inc, e.g. "AVRDUDE_PORT=/dev/ttyU3"
+.El
+.Pp
+When
+.Va AVRDUDE_PROGRAMMER
+is one that uses USB,
+.Va AVRDUDE_PORT
+can optionally specify the usb port. See the
+.Fl P
+option in the
+.Xr avrdude 1
+man page for more details.
+.It Va AVRDUDE_SPEED
+The
+.Xr avrdude 1
+programmer speed when the programmer is "arduino".
+This is passed with the 
+.Fl b
+flag.
+.El
+.Sh PROCESSOR OPTIONS
+These options for these variables default those found in the Arduino
+.Pa boards.txt
+file by the
+.Pa arduino-boards
+script for
+.Va ARDUINO_BOARD .
+.Bl -tag -width 12345678
+.It Va ARDUINO_CORE
+This is the location of the core to link sketches against when compiling.
+.It Va ARDUINO_VARIANT
+This is the variant of
+.VA ARDUINO_CORE .
+.It Va F_CPU
+The the clock speed at which the microcontroller operates at. This
+is useful when under or overclocking.
+.It Va MCU
+The microcontroller on the board.
+.El
+.Sh OTHER OPTIONS
+.Bl -tag -width 12345678
+.It Va ARDUINO_DIR
+Top level of Arduino installation. This defaults to
+.Pa %%PREFIX%%/arduino .
+.It Va ARDUINO_CFLAGS
+Additional compile C flags.
+.It Va AVR_LIBC_DIR
+Top level of the avr-libc installation. This defaults to
+.Pa %%PREFIX%%/avr .
+.It Va CPPCHECK_FLAGS
+Additional
+.Xr cppcheck 1
+flags to be used with "make lint"
+.It Va HFILES
+Specify include files that should also be processed by
+.Xr ctags 1
+for "make tags".
+.It Va WITH_CPPCHECK_XML
+When set, "make lint" runs
+.Xr cppcheck 1
+with XML output enabled using the
+.Fl -xml
+and
+.Fl -xml-version=2
+flags.
+.It Va WITH_CPPCHECK_CHECKCONFIG
+When set, make lint" runs
+.Xr cppcheck 1
+with the
+.Fl -check-config
+flag.
+.El
+.Sh NOTES
+It's important to do a "make clean" if
+.Va ARDUINO_BOARD
+or any other
+.Ic "PROCESSOR OPTIONS"
+options are changed.
+.Pp
+To allow use of the
+.Xr avr-gcc 1
+.Fl Werror
+flag, standard and local Arduino library modules are compiled
+using the
+.Fl w
+flag which inhibits warning messages. This makes it possible to add
+the
+.Fl Wall ,
+.Fl Werror
+and
+.Fl Wstrict-prototypes
+flags to
+.Va ARDUINO_CFLAGS
+(which is recommended).
+.Sh FILES
+.Bl -tag -width 12345678 -compact
+.It Pa %%PREFIX%%/arduino/hardware/arduino/boards.txt
+The Arduino boards database.
+.It Pa %%PREFIX%%/arduino/lib/version.txt
+The Arduino version file.
+.It Pa %%PREFIX%%/arduino/libraries
+The location of standard Arduino libraries.
+.It Pa %%PREFIX%%/arduino-bsd-mk
+The default location of
+.Pa bsd.arduino.mk
+and the scripts directory.
+.It Pa %%PREFIX%%/arduino-bsd-mk/scripts/arduino-boards
+Script used to parse
+.Pa boards.txt
+to determine various hardware related options.
+.It Pa %%PREFIX%%/arduino-bsd-mk/scripts/arduino-version
+Script used to parse
+.Pa version.txt
+file.
+.It Pa %%PREFIX%%/arduino-bsd-mk/scripts/gcc-version
+Script used to determine the version of
+.Xr avr-gcc 1 .
+.It Pa %%PREFIX%%/avr
+The default top level of the avr-libc installation.
+.El
+.Sh EXAMPLES
+Here's a sample Makefile:
+.Bd -literal -offset indent
+TARGET= blink2
+ARDUINO_BOARD= atmega328
+ARDUINO_MK_DIR= %%PREFIX%%/arduino-bsd-mk
+MAKEOBJDIRPREFIX=/usr/obj
+ARDUINO_CFLAGS+= -Wall -Werror -Wstrict-prototypes
+\&.include "${ARDUINO_MK_DIR}/bsd.arduino.mk"

+.Pa blink2.ino
+or
+.Pa blink2.cpp .
+The board is a atmega328. Additional compiler flags are specified.
