# How to in three steps:
#   Build (once) - Initialize (once) - Attach (every time)
#
# 1: Build Image (once):
#   export USERNAME=$(whoami) UID=$(id -u)
#   docker build -t bash . --build-arg UID=${UID} --build-arg USERNAME=${USERNAME}
#
# 2: Instantiate container (once):
#   xhost +localhost
#   export USERNAME=$(whoami)
#   docker run --ulimit nofile=65536:65536 --name mcnp6 -v /Users/${USERNAME}:/Users/${USERNAME} -it bash
#
# 3: Attach to container (every time):
#   xhost +localhost; docker start mcnp6; docker attach mcnp6
#
