### SETUP ###
# 0. Install the ethminer executable.
#    For instance from https://github.com/ArtSabintsev/Ethminer-for-macOS
#
# 1. Create a shell script with the full ethminer command, using the executable above.
#    For instance 'ethmining.sh', with the ethminer executable inside "~/bin":
#    Note also the last part '>& /tmp/ethmining.log':
#
# #!/bin/bash
# /Users/<YourName>/bin/ethminer -G -t 2 -v 2 -S <PoolAddress> -u <UserName> >& /tmp/ethmining.log
#
# 2. Make the script executable: chmod 755 ethmining.sh
#
# 3. Fill the MINING_SCRIPT_FULL_PATH variable below. It is important to provide
# the full path of the script. No ~, no ./... etc.
#
# 4. Make sure MINING_LOG_FULL_PATH points to the same file as the last part of the script above.
#
# 5. Consider a small tip, thanks! :-) ETH: 0x1Dd0e805a5DC21e40B28D4763c6Af790cd6bcd33
