# I assume that unless ENERGIA_DIR is defined that the ENERGIA core is in 
# ../../ENERGIA/cores (it should probably be relative to this file)
# I also assume that unless the MSP430_TOOLS_DIR is defined that the 
# msp430-gcc toolchain is in your path.

# 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:
#
#       ENERGIA_LIBS = Ethernet Ethernet/utility SPI
#       MCU    = atmega2560
#       AVRDUDE_PORT =   /dev/cu.usbmodem12a1
#
#       include /usr/local/share/Energia.mk
#
# Hopefully these will be self-explanatory but in case they're not:
#
#    ENERGIA_LIBS - A list of any libraries used by the sketch (we
#                   assume these are in
#                   $(ENERGIA_DIR)/hardware/libraries 
#
#    MCU    -  the name of the processor
#
# Once this file has been created the typical workflow is just
#
#   $ make install
#
# All of the object files are created in the build-cli subdirectory
# All local 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 Energia header and footer have been affixed.
#  - any number of .c, .cpp, .s and .h files
#
# Included libraries are built in the build-cli/libs subdirectory.
#
# Besides make upload you can also
#   make             - no upload
#   make clean       - remove all our dependencies
#   make depends     - update dependencies
#   make install     - connect to the Energia's serial port
