# 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 enable
#  4. To allow reload you need to add
#       W:127.0.0.1
#     At the begining of the api-allow parameter of your config file
# 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
