# Desc: Simple script to help drive the boot2docker docker with
#       parallels without much change.
#
# Install:
#   ./boot2dockerp install
#   ./boot2dockerp env
#   # Follow instructions of the env command
#   docker ps # should now work
#
#   Anytime you open a new shell, run:
#     boot2dockerp env
#
#   For ease of use, supply boot2dockerp somewhere on your path.
#
#   Important Note:
#     boot2docker has been deprecated in favor of docker-machine.
#     Use the docker-machinep command which is part of this repo.
