# In order to allow Windows, Mac and Linux to all run
# the build in the same way, we want to avoid doing
# config via environment variables, because Windows
# is "special".  The only other way I know to pass
# in params is via CMD, which if you specify here,
# then trailing args to docker run and docker create 
# get passed to it.
