# Typical usage:
#    0) install cmake version 2.8-9 or higher.
#    1) install a PizzaFactory cross compiler
#       a) darwin toolchain targeting sh-elf: http://sourceforge.jp/projects/pf3gnuchains/downloads/50061/sh-pizzafactory-elf.pkg/
#       b) install pkg.
#       c) export PATH=$PATH:/pizza/bin
#    2) cp cmake/Toolchain-OSX-GenericShElf.cmake.sample ~/Toolchain-OSX-GenericShElf.cmake
#    3) tweak toolchain values as needed
#    4) cd build
#    5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-OSX-GenericShElf.cmake ..
#    6) Run mirb on gdb
#       a) sh-pizzafactory-elf-gdb tools/mirb/mirb
#       b) target sim
#       c) load
#       d) run

# name of the target OS on which the built artifacts will run
# and the toolchain prefix
