Makefile

# This is just a dumb makefile that provides a few short-hand build targets and install
# destinations. It's not meant to be robust or efficient or even particularly flexible, but
# hopefully the simplicity makes it easy for you to use and modify to suit your own needs.
#
# This makefile also has a few examples of how to cross-compile the executables for other
# architectures, such as home routers.
