# You need to install tmux ('apt-get install tmux') a screen multiplexer.
# If you want to access the cgminer console go to the machine and type:
#     tmux

# Instructions:
#  1. Add your own parameters on the PARAM variable below.Most of the
#     parameters needed can be determined in file 
#     ${HOME}/.cgminer/cgminer.conf
#  2. Copy this file to /etc/init.d/ by typing
#     sudo cp cgminer /ect/init.d
#  3. Mark to run at boot time
#     sudo update-rc.d cgminer ename
# Now if your computer restarts cgminer will restart :)

# Do NOT "set -e"

# PATH should only include /usr/* if it runs after the mountnfs.sh script
