# machinery to run a soml program in 2 ways
# - first by running it through the interpreter
# - second by assembling to arm , pushing the binary to a remote machine and executing it there
#
# The second obviously takes a fair bit of time so it's only done when an REMOTE_PI is set
# REMOTE_PI has to be set to user@machine:port or it will default to an emulator
# the minimum is REMOTE_PI=username , and off course ssh keys have to be set up
# btw can't test with ruby on a PI as code creation only works on 64bit
# that's because ruby nibbles 2 bits from a word, and soml code doesn't work around that
